SCIENTIFIC AMERICAN, New York, May 29, 1869  The front page features an interesting print of a rather wacky bicycle called: "White's Improved Bicycle" which has a related article: "A New Style of Velocipede". Obviously it never caught on.
Many other articles & prints of inventions & improvements of the day. Complete in 16 pages, never bound nor trimmed, minimal margin wear, bit of ftpg. foxing, good condition.
