While I was ripping one garment apart I was intrigued when I found this label-
It states: Int'l Ladies Garment Union Workers with the letters "ILGUW" and "AFLCIO"
I have never seen this kind of label before and I was off to find my laptop to do some research.
I found out that this label was made between 1955-1963. "This label was issued after AFL and CIO merged in 1955, and lasted until June 28, 1963. It is usually printed in blue on white, and features a scalloped circle with a threaded needle diagonally behind it. In the center are the large letters ILGWU, crossed with a smaller AFL-CIO. Around the edge is printed Int'l Ladies Garment Workers Union."
Wikipedia offers this posting on the Ladies Union. Go and have a read if you'd like to learn about 1920's garment making and the politics behind it all.
I thought it was interesting and it was nice to date the fabric.
