Kayser, before they were Kayser-Roth, used to plug their unmentionables with the slogan “You owe it to your audience.” It was perfectly sensible for them to buy ad space in Playbill:
Waiting for Lefty, which opened on this date in 1935, occupies a unique spot in the history of American theater: it was Clifford Odets’ first play to be produced, staged by the Group Theatre, and it was a hit for both Odets and the Group. The subtitle, too long for Playbill — on this page, anyway — was “A Play in Six Scenes, Based on the New York City Taxi Strike of February 1934.” The storyline:
The piece is a series of interconnected scenes depicting workers for a fictional taxi company, but inspired by an actual taxi strike. The focus alternates between the drivers’ union meeting and vignettes from the workers’ difficult and oppressed lives. Not all are taxi drivers. A young medical intern falls victim to anti-Semitism; a laboratory assistant’s job is threatened if he doesn’t comply with orders to spy on a colleague; couples are thwarted in marriage and torn apart by the hopelessness of economic conditions caused by the Depression. The climax is a defiant call for the union to strike, which brought the entire opening night audience to its feet. The play can be performed in any acting space, including union meeting halls and on the street.
And come to think of it, rather a lot of hosiery mills were struck in the 1930s.
