The Museum Press is one of the most completely equipped letterpress shops in the Northeast, with presses manufactured over a hundred-year period from 1835 to 1953. The shop was organized in the 1980s by the late William Brady Washburn. Washburn collected so many letterpresses and other equipment that the museum trustees decided that the shop should have its own building.
