There is currently an exhibit in Grand Central of the original photos that were displyed in the Colorama. The pictures, 36 of them hung as prints in the MTA store/museum at Grand Central, are quintissential Americana scenes of familys and iconic American landscapes like the Grand Tetons, an endless wheat field in the plains, or a California beach.
It's a great sample and the only disappointing thing is that the exhibit centers just on photos from the 1960s. I would have loved to have seen how these photos and their depictions of the American family evolved over the decades. You can see some of that as womean go from more traiditional family roles (a mother in a dress playing with a daughter playing with dolls, 1962) to small hints of women's lib (a women in capri pants biking atop a mountain in the Pacific Northwest, 1967). The photos will be up until November of this year.
