These two operations give an appearance to the upper blank which closely resembles actual -platted leather straps or strips. .f By our-method and process, the upper blanks can be quickly handled and treated, and as the blanks are out before the perforating and emboss-- ing steps, a high cut 0! the hide is insured. Likewise, by our process the shoe manuiacturerhimself can do the periorating and embossing, and

While we have shown an entire upper in Figure 1, it is to be noted that vamps or other upper parts can be treated according to our process.

Other changes in details may be made without departing from the spirit or the scope of our invention, but what we claim as new is:
