This is always amusing: the wood cases shown here are Napa Valley brand. They pretty much made all the wood cases back in the day. They sell easily on eBay for $50-75. These were at a flea market today. Not for sale, just holding the 10-cent cassettes

There's a thrift store I go to once in a while with about 50 of these cases screwed to the wall. Again, cases not for sale, just holding the cassettes ....
