I showcased art before at coffee shops etc, sold post cards and a couple of prints. I had one experience when I showcased a print for an art auction I did set a min bid but the establishment let the piece go for a bid that was lower then the min I requested. I was somewhat disappointed in this but since half of it went to charity I did not want to raise a big fuss as I did make a little, it was for charity and I got work exposed. (more)
