In the early '70s, George Cruger, a young editor at the Virginia Museum of Fine Arts, began doing curatorial work in photography and buying photos (unaware of the ethical standards suggesting that curators refrain from collecting in their own fields). Cruger, whose interests are reflected in the variety of subject matter, time period and country of origin, found his images in antique stores and later on Web sites. The one unifying factor among the images: They were all cheap. So Cruger built his collection on a limited budget, but got his money's worth. Now, 100 photographs, like Elisa Felicie Amelie Seybert's "Sailor and Girl," left, are on display as part of "Photographs From the Collection of George Cruger," running through Jan. 31 at Main Art Gallery. 355-6151.
