âEver since becoming good friends though collecting shaving mugs ourselves, we have always talked about writing a book on the subject together. The shaving mug series will cover all aspects of quality shaving mugs to increase collectorâs knowledge about shaving mugs. The photographs of the shavings mugs within the books are from the authorâs own collection. It is not our intention to cover the history of the pottery, as we want to concentrate on the shaving mugs themselves.â
