Mosh pits. Stage divers. The token drunk ex-hippie who shouts “Freebird!”

Note to self: Keep baby away from concerts.

But make his/her debut a bona fide newbornpalooza with a birth announcement from Rattle-n-Roll. Created to resemble band gig posters, the announcements are made by California graphic designer Ryan Loyko and wife Andrea and feature custom illustrations of your little bundle.

E-mail a photo (plus name, birth date, and weight) and select one of five templates. Loyko will draw a portrait, e-mail you a proof, and you’re ready to rock. Announcements are printed as full-color, one-sided handbills and come with two full-size posters.

Perfect for handing out to groupies everywhere.
