Dear collective wisdom:

I'm cataloging a group of maps from the Iowa State Planning Board from
the late 1920s to mid 1930s. They look to be blackline prints but there
are several that look like negatives, though they're on paper. I haven't
seen anything else like this and was wondering if anyone else has
encountered something like this.

Thanks!
