Vintage 1940s baby sleep sack and matching bonnet

My dad wore this in the early 1940s. Very warm baby blue material with cute animal figure. Sack zips closed and has snaps by neck. One lipstick stain on bonnet as shown in photo. Otherwise in excellent condition for being so old. Approximate measurements: Bonnet 8" across and 8" long to ruffle with ruffle extending another 4.5" in length. Sleep sak 26" in length, 17" across and 9" wide by feet.
