Description
In the 1920s, riding in an elevator would have been a rare event and having one in the home rarer still. Flip up the card and watch the elevator go down. This movable paper design was patented in 1927. The smallest Sedgwick elevator sold for $600 at this time. Another mechanical card perfectly demonstrating the product it promotes.
