I have one that my DH got years ago from the dumpster behind a Ben Franklin store, it is in my garage and full of clothing patterns from the 70s and 80s.
When I worked at Monique Fabrics in 1973-74, we could keep discontinued patterns but had to return the pattern envelopes for credit so lots of my patterns are without envelopes!
Maybe I should clean it out and store fabric in it like Tartan says...
