VINTAGE BOTKIER Handbag, Ostrich? Leather

This is a vintage bag. with the city scape lining. The leather appears distressed, I am uncertain of what type of leather was used to make this handbag, was it like an ostrich leather with the spotted leather or was the distressed look was on purpose? It has a fun city scape lining. 10"x7", with a crossbody strap.
