Vintage 1960s Elby's Big Boy Wax Paper Carryout Cup/Container - Mint Condition For Sale

Here's a wax/paper carryout cup from Elby's Big Boy restaurants. This cup is from the 1960s. This 16-ounce cup was made by Dixie Cup. It's 4.5" tall and about 4" in diameter at the top. Doesn't look like a typical soft drink cup - could have been used for milkshakes, chili or something else. Or it could have been used for soft drinks. Mint/unused condition.
