It was marked $20, and we had to run to the store to get cash (this was a spur of the moment stop) and asked the gentleman to hold it. He happily obliged. We returned with our fresh $20 from the ATM and I sought out the man. We walked to the painting and he leaned over and said, "that was marked $18, right?" Right away Andrew and I told him that it was marked $20. He gave us this look like we were idiots. He started to laugh and said that this was a garage sale and we had to barter. We were both too dumbstruck to do much other than laugh.
But, we got the painting for $18. Well worth it, and I would have paid $30. I guess I'm not used to trying to sell people short : )
The artist name looks like Antonio with a frame that says "hecho en Mexico" (Made in Mexico). I'll have to do some research and see if it's anyone cool.
