Blasto from MY Pasto

Back in February of last year, when I was working through my collection of MGM snapshots, I did a post that included this photo. Once the guesses were in, I surmised that this might be Madge Blake, but as I wrote back then, I wasn't very sure. Turns out I was right about my uncertainty. Just turned on the television, which was tuned to TCM (what else?). At that very moment, I saw this woman on the screen! Yes, I shrieked. The film was, "The Yellow Cab Man" starring Red Skelton. I zoomed to imdb.com to check out the cast and an answer still eludes me. It could be someone named Edith Leslie, she was credited as "Big Woman." I could find no photo of Edith online, though I haven't given it much effort.
