I can't imagine that there would be noticeable differences in print quality with a run of only 50. More than that, I don't think I've ever heard of lower numbered prints from a series being worth more because of their lower number. If anyone's heard of an example, I'd love to hear it.

I want so much art, but I have so little money. Gah

As someone who's photographed a lot of nudibranchs, these photos are spectacular. The only good thing about these guys is that they move pretty slowly.
