Vintage 1970s Carter’s baby boy overalls blue airplane size 6mo EUC

Vintage 1970s baby boy overalls in EXCELLENT condition. Only “flaw” is some loose thread on the “quilting” by the top right button. There are crotch snaps for easy diaper changes AND the buttons at the shoulder are functional should you want to remove the overalls that way (after a blowout, perhaps). The way the tag is adhered keeps the back of the shoulder straps together. Measurements Inseam 5.75” Chest to crotch 11.5” Waist 7.5”
