This JOHN COLTRANE two-sided advertising postcard is hard-to-find. It was NOT available for retail sale, only being used in 2017 at stores to promote the Chasing Trane documentary.

Size is 5 1/2” by 3 3/4”. It is in mint condition.

Main picture shows 2 postcards (so you can see both sides), but each bid is for only 1 of them. Shipping includes private insurance.
