You’re down with Presto Chang-o. And always up for bingo. So lump ’em together and jump on board with PrestoBingo, the line of artwork for kids from the design duo behind the Baltimore-based Spur Design (they’ve done graphics and illustrations for Adidas and The New Yorker, to name a few). The limited-edition prints come in three themes — robots, aliens, and animals. There are winners like a dandelion with a lion’s face, a one-eyed robot named Gus, and a four-legged alien with starry eyes. They’re seriously modern (thus adequately cool for bigger kids) yet whimsical and fun (equally appropriate for the smaller ones). Available framed and unframed, each one is signed by the artist. So go ahead and ask for them by name-o. Available online at prestobingo.com.
