The Bickerdike Machine Papers
By Newman

Anyone interested in early machine cancels will be familiar with the name "Bickerdike", though few will be able to explain it. This book covers the development and use of the Bickerdike machine for cancellations. Research for the book uncovered the personal note book of one of the original owners of the Bickerdike patents, shedding great light on the heretofore foggy history of the Bickerdike machine.
