Found these in a house I bought, I probably have 10 of these jars. I think it's union leader but I can't find that union leader was ever placed in a glass jar like this. Too old to smoke or rehydrate and go for it? Looks like they fell out of favor in the 70s but weren't selling in glass in the 70s, this could be 100 years old for all I know. "Cellared"
