Apparently, market mathematics dictate that the value of a work of art (or any other product) is dictated by its rarity. Therefore, the more of these I create, the more I destroy their value. I'm being rewarded for laziness and punished for productivity. The world is a silly place.
Of course, in my case, this is all theoretical. I don't have a (brand) name and, having already made 15613 pictures in this series, even any theoretical sales value is approaching negative numbers. I am a silly, pointless creature. Monetarily speaking. Oh well.
