I have a couple of those. My husband uses one in summer for his home brewed iced tea. Keeps the whole thing in the fridge. Every once in a while I have to bleach it out because it's so stained from the tea. Come to think of it he reminds me of Uncle Si from Duck Dynasty. Never without his tea. Hey!
I bought one at a yard sale last summer. It is a blueish/green color and the Coleman tag is a diamond shaped raised chrome. I'm not sure of the age but the guy said it was his dad's and he remembered him using it in the 60's. I'll have to get a picture of it posted. It's pretty cool!
