Wood Type.

The Hamilton Manufacturing Co. traces its roots back to the 1st wood types made in the US.
Darius Wells produced the first American wood type in 1828; his business was reorganized into Wells & Webb, then acquired by William Page, later passing back to the Wells family, and finally sold to Hamilton before 1880. A 'type specimen' book was issued in 1900, Hamilton’s Catalogue No. 14, which displays US typography of the 19th century.
