Advance 5260 vingtage 1950s sewing pattern child coat legging hat size 8

This is a vintage pattern from Advance, number 5260. This probably dates to the late 1940s or early 50s but I could not find a copyright date. The pattern pieces are of the precut variety common to that era. The pieces are all intact with no pin marks or evidence that they were used. The pattern is in size 8, breast 26. It is for a coat with two variations for buttons; a pair of leggings and a hat. The envelop on this one shows some yellowing but is intact.
