Vintage Two-Seater Velocipede Illustration - Historical Bicycle Design #1618490 (License: Personal Use)

This black-and-white line illustration depicts a mid-19th-century tandem velocipede, an early human-powered vehicle with two large spoked wheels and two rider seats aligned front-to-back. Pedals are mounted on the rear wheel axle, characteristic of pre-chain-drive bicycles, and the frame is constructed from simple tubular metal with minimal ornamentation. The design reflects the transitional phase between the dandy horse and the modern safety bicycle.
