This is a selection of 20 vintage 1970s used Art Lettering and Drawing Calligraphy Pen Points Markers each marked ROSS F. GEORGE SPEEDBALL HUNT MFG. CO. Made in U.S.A. I found “The Speedball pen was developed and patented by sign letterer Ross F. George of Seattle. His square-tipped pen could make broad and thin lines. George took the patent to the C. Howard Hunt Pen Company in 1915.” I am including twelve C-0, four C-1, one C-2, and three C-5. They are used with wear, scratches, ink and rust. They were not tested and have copper colored tops. They were cleaned.
