Oh Boy designed this whimsical and endearing wedding invitation for close personal friends. Drawing inspiration from the location of the wedding reception—the Enoch Pratt Free Library in Baltimore—the invitation takes the form of a 1950s-era grade school primer. Included with the invitation is a report card–style comment card, rating the couple’s performance in areas such as “Bouquet toss (distance and height)” and “Apparel and general hygiene,” as well as library-style cards as response cards.
