Thanks for the kind comments.
Just to verify that these are true paper negatives, here's a positive photo (and a negative) of the negatives (chuckle).
I took the quick way of scanning them and inverting the scans using Photoshop to get positives for the original post.
Tomorrow I'll lay a negative face-to-face with some photo paper, lay a sheet of glass over the sandwich and expose it under the enlarger.
That'll take a bit longer, since I'll need to determine the ideal printing times and play with dodging and burning.
(The curtains, for example could use some burning.)
Caution: paper negatives are contageous...
