That's what I found written on a box of 40 4x5 negatives from my parents wedding in 1952.

I was so thrilled to find these, as I'd never seen the wedding photos other than one or two in all the years.

I was amazed at the stiffness (thickness) of these negs, their condition and quality.
I scanned all of them to make a book at A&I for my xmas gifts to my siblings, one for the archives.

Yesterday I printed from one for a cousin...I didn't even re-wash..just printed and damn good negs (mine don't print this easy).

Some guy with a speed graphic & flash did these 56 years ago.
That alone says a lot about film, it's usability and archival qualities.
Here's a few samples.
