2 Cent Documentary Battleship Calender

This is the July 1898 page from Henry Tolman's 2 Cent Battleship Calender. It is typical of the forward months of the calender through the tax period requiring these stamps. Most of the dates are occupied by cancels from railroads. Some dates the origin can't be determined and the remainder dates are completed by banks, industrial concerns, and other companies.
For those unfamiliar with calender collections of the 1898 tax period, dates are filled in by stamps cancelled for each date the tax was valid. July 1898 was the first full month that individuals and businesses were responsible for the taxes payable through stamps during the Spanish-American war. The month of July is complete for most dates except for four Sundays, when business was not normally transacted.

Michigan Central RR July 1, 2, 4, 14, 16, 22, 23, 30, 31
