One of seven abbreviated weekdays from a perpetual calendar set – unfortunately, I do not have the months or figures. The reversed out typeface is Latin, Peerless, or Old Style Antique, characterized by sharp, wedge-shaped serifs. This style of letter appeared as wood type for the first time in 1879.
8 line Hamilton Calendar Figures, style No. 6309
According to the 1938 Hamilton specimen, “All calendar figures in any one size and style are made up in uniform size blocks. A set includes figures 1 to 31, fractions, and seven blanks.” The price in 1938 for an 8 line Calendar Set (as just described) was $13. All of the figures and fractions are present in my font, sadly I am missing the seven blanks.
