December 11, 2009 OXON HILL, Md. — Just Born, maker of the chick- and bunny-shaped marshmallow Easter treats called Peeps, is officially opening its first store devoted to well-known products. The shop sells 850 Peeps products, including plush toys, clothing, china and a hand-blown glass Peep. The store is a monument to the marshmallow creations, with ultra yellow awnings, chick-shaped door handles and 3-D chick tilework behind the register. Most of the offerings are not edible, but the store does sell the spongy chicks, which have a shelf life rivaling Twinkies and were first produced in the 1950s. An artist, who crafted artwork with Peeps for more than a decade, will display some of his work is in the store…said one spectator to the artist, "Thank God you found something to do with those things other than eat them.” XCh. 18 (air pollution) XExam Dec. 17 (Thursday, 10am-12) äCh (fossil fuels to air pollution + presentations) Peeps store opens near D.C., a monument to marshmallow STERLING, Conn. - A holy cow in Connecticut, perhaps? Or maybe a divine bovine?
