This link will take you to a beautifully presented online catalogue of the works chosen for the 2013 International Printmaking Exhibition at Kazanlak in Bulgaria. Well worth looking at if printmaking is your thing. It has excellent photographs of all the works properly described in terms of the method of printmaking employed by the artist. Also information about the jury etc. The deadline for submissions for the next exhibition is around April 2014 so plenty of time to work on something to submit. There is a cost though, which I haven’t checked. It can be quite expensive (some bienalles cost as much as R1000 and you may not even be accepted which is a bit off putting).
Do look at the book full-screen to really see the prints properly.
I have the entry conditions etc so if you’re interested in submitting work email me and I’ll forward them to you.
