I was browsing art today on eBay, as I am trying to find something for the huge wall above my couch, and I came on this delightful work by Catrin Welz-Stein. It reminds me of how the Sea of Ships boats in Poorthwart might look, if it were an elegant dream world, as opposed to a manic, ever-deteriorating sketch that is meant to evaporate the way that dream memories do. (Disclosure: I was not aware of her work when I designed the boats).
I recommend that you go enjoy more of her work on her website, and use that as the source to buy any prints of her work. (No doubt, the eBay links are going into someone else's pocket). I found Catrin's prices on Red Bubble to be extremely reasonable, so I encourage you to check out her wonderful stuff.
