Have you seen the Land of Nod's new Studio Nod?  They are offering a curated selection of artwork from several of the artists they collaborate with, and it's such a wonderful collection!  They are investment pieces, to be sure, but all are pieces that would last for years to come, and grow with baby, so it's a fantastic option if you are looking for original art pieces.  This board is centered around Lisa Condon's On a Whim, and I love all the punchy, imaginative colors.
