Library Cards: Now for babies!

Okay, that's not really a change for us but it was a catchy title. Last September, for National Library Card Sign-up Month, a staff member created a display letting folks know that any age (and species) can get a card, as well as some of the lesser known benefits of getting a card. Sure, these families are already in the library but many of them don't realize even the youngest family member can get a card in our system. DISCLAIMER: The family pet can not actually get a card. Sorry. Our Display Maven made use of ALA's promotional material found here.
It was adorable so we've left a smaller version up! We have several locking acrylic boxes that are perfect for this type of display. What have you done to promote card registration?
