Dorothy Sebastian and Joan Crawford did three movies together from 1929-30.
Our Dancing Daughters (1929),
Montana Moon (1930) and
Our Blushing Brides (1930). Here are they are taking time for some publicity shots - the last shot suggests it is for
Our Dancing Daughters.
First they eat.Then some calisthenics are in order.
A friendly boxing match in which Joan slugs Dorothy (just so you know who's the lead).
And of course some ping pong? Yeah, that's how I'd finish it up too. Name the net judge and win a prize.
