Found this set of showgirl publicity photos a few weeks ago at the BrooklynFlea. Not sure if they're for a stage production or film. I need to do some research but I'm running out the door so I'll just post and hope somebody recognizes a face. (click for larger versions)
Signature looks like "J. K. Milligan" and maybe "L.A." or "U.A."
Any Vaudeville/Broadway buffs have any clues?
