Vintage 40s M&H Sport Stores Lifeguard top, looks like size small (see measurements)
This appears to be a wool lifeguard top produced by M&H Sport Stores in the 40s in the Philadelphia, PA or Atlantic City, NJ area. It is a felted wool material with felt number 128 stitched on the back. It is missing a patch on the front that seems to be lifeguard related.
There is some fading and holes but it's remarkable how intact it is for it's age. A truly special piece of history!
