Old drawings
Once upon a time many years ago, I was in a financially unpleasant situation and I hatched a plan: I would paint and sell some pictures (of seashells, because of course). That plan never got even as far as offering anything to anybody, but I did paint some pictures. Shells are fun to paint, and you also get to feel like Ernst Haeckel or some other scholar-illustrator of old.
Can you ID all the shells?
(I don't intend to sell the pictures anylonger, don't get the idea that this is an ad.)
