Various modifications may be made in the above embodiment of my invention without departing from the spirit and scope thereof as set forth in the following claims.

I claim:

1. The method of making printed leather which comprises completely tanning a skin to produce leather,a-apply. a liquid cellulosic colorholding base to the entire surface of the tanned skin, printing a design upon such cellulosic lease,v

with a pigment carried in a casein medium, drying such printed surface, applying a thin: coating of a cellulosic material over the printedsurface, drying such cellulosic coating andthereafteffinishing the surface of the skinnby a ,glazing-operation. 1

2. The method of making printed leather which comprises completely tanning a skin to'prddu'ce leather,.white-.coatil1g the entiresurface ofrsaid leather, applying a liquid cellulosic coating over said white coating, drying said coating, printing a design over the cellulosic coating with a pigment carried in a casein medium, drying such printed surface, applying a thin coating of a cellulosic material over the printed surface, drying such cellulosic coating and thereafter finishing the surface of the skin by a glazing operation.

3. The method of makingprinted leather which comprises completely tanning a 'skin by-a-chrome treatment to produce leather, applying a liquid cellulosic coating over the entire surface of the tanned skin, flattening the skins by subjecting ithenT imiheavy pressure between hot plates, printing a design over the cellulosic coating with a casein h'eld pigment, drying such printed surface applyingapthin coating of cellulosic material .-oyeruthe printed surface, drying such cellulosic coating, and thereafter finishing the surface of 'theprinted'skin by a glazing operation.
