"Mailing Tracts" from 1919

vienne

For a research project, I need clear scans of all of the 1919 small-sized tracts meant for through the mail witnessing. Can you help?

I didn't know there was such a thing. I'd be interested in seeing some.

Try archive.org, Library of Congress may have them as well, although you may have to physically find them or ask a librarian.

Already checked archive.org and library of congress. They do not have them.
