As we continue to sort through Man's Mother's goodies, we continue to turn up some interesting tidbits, like
There are 23 leaves in this packet, at least one was used. I did a short Google search, sure did not find much. The image results I found during my search showed different covers, obviously aimed at different markets (one was for fishermen). I checked Google Books, and could only look at a snippet view. I looked at that snippet and it seemed to indicate a possible patent number, so next I went on a patent search with that number and with a word search of "lather leaves" and even added in the year (1943). So far, I am still searching.
If you know anything more about Lather Leaves, I would love hearing from you.
