CDV size card with albumen image. Image is the invention of Zadoc P. Dederick. Inscription on verso "Geo. O. Bedford's Park Gallery, 166 Broad St., Newark, N.J. Entered according to Act of Congress, in the year 1868, by Zadoc P. Dederick, in the clerk's office of the District Court for the district of New Jersey." Dederick invented The Steam Man and patented him in March of 1868. The Steam Man was a steam powered pair of legs rigidly attached on a horizontal swivel to the front of a carriage. Hence the carriage was able to be steered. The body of the Man is the boiler and the driving cylinder is mounted on the back. Seems like this CDV was used along with the patent (#75874).
