Publications of The International Machine Cancel Society

Please see special announcement regarding print book availability from the May 2021 Forum.

Over the years, members of the Society have created a large number of publications about machine cancels, their inventors, manufacturers, and the markings themselves. This is an important goal of the Society: passing along critical knowledge. The publications are for sale to both members and the general public. Machine Cancel Society members receive a discount on the publications they purchase. The following Adobe Acrobat file has the current pricelist of publications offered by the Machine Cancel Society. The current list is dated May 2016.

Regarding The Sale of Frederick Langford's
Books by The International Machine Cancel Society

The estate of the late Frederick Langford has sold all remaining copies of Mr. Langford's books to the Society for resale to members. It cannot be emphasized enough that Mr. Langford was the authority on American flag machine cancels.

The Flag Cancel Encyclopedia, along with Langford's book on Doremus machine cancels, are now available from the Machine Cancel Society. Mr. Langford sold the books for $50 for the 2008 edition of the Flag Cancel Encyclopedia, and $20 for the 1988 Doremus. The Society now sells them for 1/2 retail plus postage, or $29 for the Flag delivered in USA and $12 for the Doremus delivered in USA, or $35 for BOTH books delivered in USA (yes, you read that right, a much better deal if you buy both books!) They are a bargain. Both are hardbound, too!

If the books are shipped overseas, they are priced at US$25 and US$10 plus postage (approximately US$20). If both books are ordered for foreign delivery, please add $20.00 for shipping so both books are available for only $55.00.
