I love the old ads, they were clever and cute; this one is no exception. On the inside cover of this Tums match book, is a little poem- a take off on Mary Had A Little Lamb. It says "Mary had a fussy tummy, her face was as white as snow; now every place that Mary goes-TUMS are sure to go".Also it states that if you send in the cover, along with a stamp you will receive a thermometer from A.M Lewis Medicine Co. Nice condition with only 4 matches missing.
