Dietzgen Gem Union Drawing Pen

Dietzgen Gem Union Drawing Pen

Usage conditions apply
This 5-3/8" steel, German silver, and ebony drawing pen is marked on the blade: E. D.–Co. UNION. A piece missing from the top of the handle may have been intentionally shaved away instead of accidentally broken.
As part of its Gem Union product line, the Eugene Dietzgen Co. of Chicago sold similar drawing pens, described as 5-1/2" long, in 1904 as model 502 for $1.20 and in 1926 as model 623 for $4.00. Engineer William J. Ellenberger (1908–2008) owned this pen. For his biography, see 1981.0933.25.
