Chicago 50 - No. 39 - Poker Game

"I liked Velma because she was a straight shooter, so to speak, blunt and practical. To give you a flavor, one of my favorite scenes in the musical is when the female inmates are playing a game of cards. One by one, they cheat. June sneaks a card from under her chair. Liz pulls one out from her wig. Annie has one hidden in her cleavage. All this time, Velma is smoking a cigarette. Finally she exhales a puff and deftly extracts the card that's been in her mouth all along.

Funny enough, there are photos of the real murderesses from the Cook County Jail playing cards in their cells. Buelah (the real Roxie) and Belva (Velma) and Kitty (Go-to-Hell-Kitty) are shown playing cards in 1924.
