My DH collects records and radios and 8 track tapes and we have an 8 track player. He has old player piano rolls and collects cassette tapes and has some of the victrola records. He has some records that were home taped by someone. Nobody we know just something we added to the collection. We have a case of old tubes for radios and old TVs and we have a case similar to a record player case that is the unit to test the tubes to make sure they are good. I remember going to the local drug store and testing tubes for the TV on their tester. It was a free public service. We were married in 75 so this was that year. He has a record set that has the radio announcer telling about the hindenburg disaster as it happened. He has more than I can remember. We are always picking up stuff to add to it.
He also has a coke and pepsi collection that includes a lot of the old and older cans and bottles you won't see now. Do you remember YooHoo pop? There was a Double Cola out in the 70s and I remember when all you could choose from was Root Beer Coke and orange or grape. I have a box of caps in my collectible collection for bottling your own Root Beer at home. It came with a flavor packet. There were all sorts of pop you don't see anymore. I don't think they make Squirt anymore do they?
When I went to Mexico on a school trip in 72 we were told we couldn't drink the Coke there as it still had cocaine in it then in Mexico but not the US. Coke began with cocaine before anyone figured out that was a bad thing!!
