intended for public distribution, hastily & crudely assembled
ashcans were produced in minute quantities strictly for the
purpose of securing a copyright.

it seems that publisher M.C. Gaines and his business partners
at DC, immediately upon their realization that Wonder Woman
was going to be a huge hit, rushed this ashcan into production
to secure the trademark for what would become the world's
most popular female superhero.
