These Baby Flash Cards by Wee Gallery are absolutely adorable. I love the fun, playful illustration style set in black and white. Even if you don’t have a little one around, you could frame the wee works of art to create your own wonderful wall art. You could also turn the flash cards into a cool urban mobile with a nifty stainless steel mobile kit. Ingenious!
ETA: Ooh, it looks like Wee Gallery actually has two additional new sets of flash cards, garden and jungle, available from their site. I must collect them all.
