The 2018 exhibition(s) will open on November 9th. A submission deadline hasn't been set officially yet, but experience has taught us not to be so insanely last-minute as we were in 2017... So it's unlikely that we'll be taking stuff after September.
Please note that this year we hope to put more emphasis on original artworks and signed prints. If you're interested in selling your works these tend to do much better, and it saves us printing costs and time. We are open to digital submissions too though.
