I’m very familiar with the Japanese poster you are referring to. I own both folded and rolled examples of it. This poster is different!
I meant it imight be a japan official repro from '75 of the original Hong Kong poster - which was inserted into the japan LP record sleeves as a bonus btw
This is found factory folded but i guess there could be rolled specimens out there of this "LP record poster" but never seen one rolled in 20 yrs and would question it if i saw one for sale.
The real '72 HK 1sh was never on glossy paper like this or rolled....usually the real ones are much darker than the glossy bootlegs and almost forget about finding mint specimens - huge chunks or missing pieces not uncommon , its a huge problem with bootleg 70s/80s HK 1shs , ive yet to see real HK rolled , 99.9% theyre fakes - they were always factory folded. Most rolled glossy bootlegs come out of HK.
Never seen any kung fu fakes from Singapore though , they are a lot safer to buy.
