Snail Mail, a focused installation of photo correspondence from the MFAH collection, features objects that were, until recently, a common phenomenon in the photographic community. Before widespread use of e-mail, photographers would write letters on the backs of misprints or even fine-art quality objects. The MFAH photography collection contains more than 1,500 such objects that have been mailed to museum staff throughout the years as correspondence from photographers around the world.
