I'm offering a vintage book published by the Grand Lodge of the Free and Accepted Masons of Wisconsin.  It is titled "Single Letter Cipher with Monitorial and Floor Work for Symbolic Lodges under the Grand Lodge of Free and Accepted Masons of Wisconsin".  It has 222 pages to include diagrams/illustrations.  The book and spine has no writing to identify the contents.  It measures 4" x 6 1/4" x 1/2" or pocket size.  It is a nice historical document/book for Freemasons.   Thanks for your interest.
