Cooler than Cool

Something is missing from this swell Thermos cooler I scored from my friend's mother-in-law for $3 at her garage sale. You know her as the Highlights lady. I can't even imagine what else she's holding onto from back in the day...It definitely needs some soda-pop, a few Hamm's for daddy and some smartly wrapped sandwiches. Looks like we have a picnic to pack!
Hope you're having a sunny Sunday!
