Rubbo's made-for-kids philatelic tale starts with young sting-merchant Tommy Tricker smooth-talking his wimpish pal Ralph out of his father's most treasured stamp. In the doghouse, Ralph and his sister Nancy spot the rarity in the local stamp shop. No chance, $ 600 price tag, but the dealer offers the pair a dusty old album as solace. Lo and behold, out pops a hand-written letter dated 1928, stating the whereabouts and means of recovering several old and extremely valuable stamps. Ralph is reduced to pinhead size (by way of some fairly clever animation), planted firmly on a current 1st class stamp, and popped in a letter-box. En route to his final destination, the film gets bogged down in various worldwide locations: the whole thing could quite easily be condensed into a 45-minute TV short.
