What is art?

I received two different opinions on my art pricing at the December 3 ArtWalk from two different people.
The first said that my prices were just right. “Not as high as New York City, but this is Billings, and this is just right.” She said this as if she were suggesting I could charge even MORE than I do (and she did like my work).
The second one asked, “Why is your art so expensive,” overlooking all of the cards and reproductions that are priced from $3.50 to $25.00 (which is not expensive).
I had to take a deep breath, remember who I was and where I was before I responded, “I actually don’t think it’s expensive when you take into consideration how many years it took to learn to do this, how long it takes to make each work, and all of the expenses that it takes to maintain my studio and communicate with potential collectors. Here–let me show you some very affordable pieces…” at which point I directed her to cards and prints. She didn’t buy anything.
But I like this response better, because it gets right at the heart of the value question. Thanks, Seth Godin. ????
