This is a standard/chrome postcard gently poking fun at some major political figures of the time. It's copyright 1982 (making it one of the more recent standard/chromes), and is signed (again signed, not autographed) by Art Strader, who apparently did a series of these.
Ronald Regan was president at the time, and he had a well known fondness for jelly beans - hence the bean theme. Jimmy Carter & Richard Nixon are the "Has Beans", Regan is the "Jolly Beans", and Ted Kennedy and I think (but not sure) Jerry Brown are the "Would Beans".
I haven't seen cards like this very often, and I think it's interesting.
I wonder why Gerald Ford wasn't in the group? And is that really Jerry Brown?
