1898 Revenues: G. H. Mumm Printed Cancels: Joyce Type 3, 2 cent 1900s

Here we have Joyce's list of 2 cent proprietary GH Mumm cancels with a 1900 year date. Note that there are no listings for January, May, July, or October. However, below are images for the cancels from January and May. I expect that there may also be July and October cancels in existence based on the cancels on the 1 cent proprietary and the pattern of use by the Mumm firm.
