DONNY & MARIE OSMOND I'm Gonna Knock On Your Door (Polish 7½" x 6" colour postcard with a playable clear 1-sided flexi disc attached. The postcard itself features a vibrant cartoon flying creature and flowers scene which is not related to thesingle in anyway, but has artist/title text printed on reverse. A fantastic obscurity with a wonderful mis-translation of 'Danny' printed on both the postcard back and on the artist/title printed paper envelope. Due to its fragile nature, thethin paper envelope shows signs of wear, the flexi is in superb condition - A fantastic oddity!)
