Do you mean to say this person might still be working and selling his "palette knife works" there on Madrid's Plaza Mayor or would other artists be selling them there? Pardon my ignorance on the topic.

Ahhh.. maybe now it's sinking in. You're trying to appraise the works you have, is that right?

I'm going to guess this Martín Hidalgo is no longer selling his works on the Plaza Mayor after 27+ years. In my walks around the Plaza Mayor I haven't noticed any artists other than the colored-pencil type. Anyone else see "palette knife works" there?

By the way, I've moved this topic from the "Favorite Places" forum category to the "About Spain" forum category since you're looking for work from a particular artist. Good luck!
