Front and back of a fold-out from Shull's Bakery (aka The John Shull Bakery or the Shull's Steam Bakery) of Marysville, PA. Just taking a stab at the correct decade.

There's still a place called Specialty Bakers, Inc. in the same city, so perhaps it's the same place with a different name. If anyone from the PA area knows, I'd love to hear from you.
