Here's a 1970s PSA for the Arthritis Foundation. 

Begins with people playing bridge, a card game, at a table. A close up reveals the cards one player is holding. Other people are also playing bridge at nearby tables; as it turns out, this is a bridge tournament.

At the end, the voiceover tell us that, “The cure for arthritis just might be in the cards."
