Does anyone remember the eagle mug Jack drinks from? Here it is (could only find B&W):

I always wondered if it was a 1975 bicentennial thing. In certain kitchen scenes it looks like he has a matching eagle salt and pepper shaker set, too.

And here is the original poster on their refrigerator in Season 1:

I still have yet to find the poster that came (and stayed) in Season 2 and beyond. It's a wine poster.
