Blickensderfer typewriter layout, as used on travel typewriters invented by George C. Blickensderfer (1850-1917) in 1891 and manufactured by the Blickensderfer Typewriter Co., Stamford, Connecticut, USA. Note that this keyboard had three rows of keys instead of the more common four, and special symbols were accessed with a special shift key.
It's a keyboard layout in the Courier New font. Both are public domain. My rendering is also public domain.
