The title is very informative. New York's Broadway from the nineteen thirties to the forties had at least one of these plays drawing crowds at any given moment. they are:1934 Merrily We Roll Along (Kaufman and Hart)
1936 You Can't Take It with You (Kaufman and Hart; Pulitzer Prize winner)
1937 I'd Rather Be Right (Kaufman and Hart)
1938 The Fabulous Invalid (Kaufman and Hart)
1939 The American Way (Kaufman and Hart)
1939 The Man Who Came to Dinner (Kaufman and Hart)

This was a Modern Library Anthology, and is a very buy should you find a copy. The only missing play from their collaborations is 1940's George Washington Slept Here. ( )
