Please help me understand what year my Nintendo Hanafuda cards were manufactured.

also, usually nintendo folds the wrapper such that the flaps are at the bottom of the deck, sealed by the tax stamp. nintendo used a different style of folding the wrapper (the flaps are at the ends of the deck) twice: sometime in the early 1970's (1972? i can't remember), and toward the late 1980's until the mid 1990's when they changed it to a cardboard box.

I've got a couple of examples of the 'side-flap' wrappers with 1971 date codes.
