ABC book of crocheted edges and corners published by Asmus Bradley Co. is their book No. 3. This booklet is 15 pages long and is full of instructions for many edgings and corners.
There is no date on this booklet but I believe it is 1940s or early 1950s. There is a tiny bit of separation at the top and bottom of the cover and a little edge wear. All-in-all this vintage crochet booklet is in very good condition. The original owner's name is written on the cover.
