National Leather Manufacturing Company Shoulder Bag WD10

And now the bags themselves.  First up is WD10, the shoulder bag.  This example is a solid red, but I have seen them in plaid as well.

Catalog detail stating that WD10 comes in assorted plaid and plastic colors.

The material on this is pretty strange (called texon) which feels sort of like vinylized cardboard.  Whatever it is, it is stiff and brittle after 60 years.
