From Dave Price

In the very earliest Kodak days, you sent the entire camera back to the Eastman company. They would process the film, reload the camera and return it to you. The prints you got would be mounted like this. This is an 1890s Ringling parade taken from an upstairs window. The fifth elephant in line seems to be an African, I assume Fanny. They didn't have this many elephants prior to 1893, so the pic would be no earlier than that. Buckles: the elephants are not trunk-to-tail for the march- when did that custom begin? The wagon partially seen at far left was one of a series of cages built by Moeller Bros in about 1893 to replace cages lost in a train wreck in 1892. This particular one was left at Baraboo in 1918 so did not go into Bridgeport when the shows were combined. It was later one of a group bought by the brothers King and was on their Walter L Main/Gentry Bros show. "No idea when that practice started, good idea tho since it keeps their minds on the business at hand and also eliminates throwing spit on a long hot march." Buckles
