Adorable 1970s (?) vintage baby red truck corduroy overalls USA made health tex Snap closures, buttons on the shoulder straps. Beautiful preowned condition given how old these are. There’s one snap (see photo) that won’t snap but I’m going to see if I can fix it, no promises. The outfit is still full functional.
