That is awesome. Not sure what you need help with on it, but it's definitely true vintage of that era (mid 80's).

Took me awhile to catch on, but I finally learned my lesson to do BINOBO on cool stuff like this. Sold one of the same vintage a couple years back for half that price at auction. Still kicking myself on that one.
Okay vintage experts, I need some help. I've had these sitting around in a pile for about 6 months, just rediscovered them today. Paid top dollar for these so I hope they're a gem? Really having a hard time finding anything about these / dating them, but they feel old as hell, way older than the Big E Levi's I've found in the past. Halp.
Awesome find. Unfortunately bib overalls don't bring in the most money in the vintage workwear category, but a great find regardless. This stuff is scarce! Placing a date on these is tough, but if I had to guess, I'd say 40's.
