Somewhere around here I have a can of Colgate shaving cream that we
found in my FIL's effects. I don't know why he still had it, but it
dates from around 1968. There is no bar code, of course. The price
(79c) is printed on the can. The can *still* works and the shaving
cream remains useable. Now there's a product.
