This set is a vintage piece that looks like it dates back to between the 1950s-1980s. The tag has been washed away to where no brand name or RN can be observed, but you can just barely read they were made in the USA. If I had to guess the size, I would say newborn to 3 months. It is very small. The pieces both feature embroidery of animals on trains and a cute scalloped trim. The only stain I could find is on the hood (see photo). No stain removal has been attempted. The only damage is that the button on the overall needs tightening/restitching(see photo). This is a unique set for any vintage collectors baby closet.
