Here is a nice vintage Deluxe Version UNO Game by International Games of Joliet, Illinois, model #3001, circa 1983/1976

This is the "double" version that is meant for those big family vacation blowout games!  There are two card holders and plenty (actually more than plenty) of cards.  There are at least three full decks here plus lots of extras.  

One deck is newer and in fine condition, and the others are showing their age. (Plus there are some odd orange colored cards thrown in there that are from some other time; see the photos.)

The score pads are from from 1976 and 1983 and though clean and usable, they are a bit faded.  

This is not a game I grew up playing, but was one I grew familiar with while working on a psych unit back in the day.  It seemed to be a game enjoyed by both staff and the patients...  I think this was true perhaps because it is not a competitive game, per se. Also, the play has a certain predictable cadence, it is just simple enough to be complex, and it always has some closure to it.
