MORE INFORMATION

For those of you who missed the exhibition last year, the postcards are all 6 x 4 inch wooden boards. Each board costs £10 and all of the artworks created are priced at £50, with £5 going to charity and the rest going back to the artist if the work is sold. Each piece is displayed anonymously so buyers don’t know who’s work is who’s until they buy it.
Just like last year there isn’t a theme to the show and we encourage both emerging and established artists to get creative! We had an incredible collection of styles and techniques last year and are really excited to see what artists come up with this time around.
The show was a huge success last year with just under 100 artworks sold and nearly £1000 raised for Charity, targets we’re aiming to beat this year with your help! It was amazing to see the variety and creativity of all the works on show and the whole collection was so well received by all who visited during the Cheltenham Literature Festival.
This year we are proud to be supporting P.E.A.K, an organisation dedicated to supporting families and educators who live or work with children pre or post an autism diagnosis. Their mission is to give support and training in practical strategies that address challenges faced whilst navigating the autistic spectrum. Find out all about them here.
Boards will be on sale at the Gallery during the dates stated below, but if you need us to post any boards to you directly, they can also be purchased at the bottom of this page until 20 September. All boards must be registered and returned to us by 1st October 2025.
after the success of last year, our postcard exhibition returns to sixteen gallery.
artists of all levels and experience are invited to take part in making a postcard size artwork to be displayed and for sale during our two week show.
This year's Exhibition will run from 2nd - 15th October to coincide with the Cheltenham Literature Festival.
guidelines and faq
There is no theme! The only constraint is that your work must be contained within the board.
You can use any medium you like. Last year this ranged from oil paints and pastels to watercolours, to photography and ceramics. Let your creativity drive you!
Depending on what medium you are using, you can choose to prime, stick-onto or work directly on the board. As long as the finished piece is constrained within the dimensions of the board, there is no restriction on what mediums you can use!
You can only use the boards from this year. All entered boards must have the 2025 label on to be included in the exhibition.
Yes, boards must be purchased from us. If a board is submitted without the 2025 Sixteen Gallery label on, it will not be valid for inclusion in the exhibition.
Once you have completed your artwork, before you either drop-off or send your board back to us please fill out the registration form. This streamlines our process, making sure that we have all the details for your artwork and allowing us to have your account details ready if your work sells.
The form is simple and quick, please fill out one for each board you have using the board number on the back. You can register your boards here.
You can return your finished boards to us using our drop-off box in the gallery on the dates given here. Alternatively you can post them back to using the address shown above. Please take a moment to register your board before you return it.
All communication regarding the Postcard Exhibition will be through email. We will notify you this way if your work sells
The postcard artworks will be stuck onto the walls using velcro strip, unless the work is heavy / sculptural and will be placed onto plinths. Please bare this in mind when creating, and make sure artwork is secure if stuck to a board.
Any unsold work must be collected on or before the 15th October before 5pm. If you have not been notified that your work has sold, then you will need to collect it. Anything not collected will be disposed of.
If you are unable to make this date, or do not want your artwork back, please get in touch with us at: hello@sixteenonline.com
We have not yet confirmed the charity we are supporting for 2025, but we look forward to announcing this soon.
£5 of the sale of each board will go to our chosen supported charity. Some artists may choose to donate the entire £50 if their artwork sells. This is completely optional, and if you would like to, check the box when you register the board, or let us know if you decide later.
