60s Lee Denim Jacket Curiosity

[Wndr]

Hi all,
I bought this Lee trucker jacket even though I couldn't remember ever seeing the logo spelled in all caps (on the pocket). From what I can find in other corners of the web, it seems like all caps LEE was used / is legit (I think someone said it was used on their workwear line?), and the ribbon tag suggests 1960s, but it still seems like there's something fishy - none of the tags spell out the model numbers which are usually pretty visible. Anyone out there know their Lees? Or anyone want to guess if this is a bootleg, or anything interesting? Thanks!
