Rattle-N-Roll makes custom birth announcements styled after rock show gig posters. You select a template and send a photo, they do an illustration and send you a stack of handbills with your baby's face on 'em. The FAQ implies that they also sell actual poster-sized prints for hanging on the nursery wall.
Currently no pricing information available for the handbills, but it looks like you can get two full-sized posters for $400.
