While doing some research I found out that this particular block was used for embossing.
The image on the block is a negative, meaning the image is recessed. For off-set printing with a standard printers block, the image is positive with raised details.
It would most likely be used for embossing a book cover or probably used for creating a raised graphic on a thick greeting or personal card.
As far as date goes, I've been told that it could have been made by the American Type Foundries from the 1890's (Which would fit the equipment shown on the block) to the 1920's and that some markings on the block show signs of heavy or prolonged use.
