Help identifying Osh kosh overalls

Hi there! I found a pair of Osh Osh children's overalls and I was wondering if anyone could help me identify them. Do modern overalls say "vestbak" on the label on back or would that mean they are vintage? Thank you!

 

Do you have a photo of the front, close up of the fastening devices?

 

Hi! Yes I do but it's not letting me upload Let me see what I can do!

 

There you go!
Thank you so much!

 

I think these are 80s-90s. A great brand and a classic.

Vestbak is a model not necessarily a vintage dating 'device.' For dating, I went by the fastening pieces.

 

Thank you so much! I appreciate your help

 

My pleasure!!
