I don’t think I have ever sent mail art to Hungary, so I am doubly sorry not to have opened my first mail art from Rebell until now. Note the deadline was last month .
This sounds like an exciting exhibition with a great concept and theme, so if you are in the areas, visit! I will try to send a piece of mail art (not for the show) sometime soon.
As an aside, I have a health challenge that has set me back, so be patient. I will catch up and send you mail art soon!
