OshKosh B’Gosh child’s Coveralls

[Annette McConnell]

Hi I have an adorable child’s OshKosh B’Gosh pinstriped coveralls that I am trying to figure out the age of them and if they are true vintage.
I have searched to find a similar one but no luck. Found bib overalls but not coveralls. I guessing they are infants size 12 - 18 months. The only tags I see is the one on the front and a small one on the inside that only has washing instructions. Any help would be appreciated

Do you have a pic of the care label? Thanks!

Yes I do.

These are also so tough to date because it's a classic and ageless style but I think these might be 70s.
