It's from McCall's and the envelope does have a slit in the bottom. However, the envelope is still whole. All the printing is fine and visible.
The pattern pieces were all cut out and I only counted 14 out of 17 pieces. But, there's even some of the transfer for the bonnet and collar.
If you don't sew this, keep this as a part of our History. Because, that's what it is.
