VTG Washington Dee Cee Sanforized Yellow Button Fly Bib Overalls 4A Kids 20 x 12

20" waist(waist measured flat is 10 and then doubled to 20") 12" inseam
Tag reads 4A, so just guessing possibly a size 4.
These are in very vintage condition showing a lot of wear
There are stains and a hole near where there is a missing buckle.
All over fading.

We have not treated these at all, so unknown if any of the stains will lift.
