Steel into Cannon
All Resolutions
Description:
Workers are hammering steel on an anvil in a busy factory workshop as cannons are being hoisted around and a steam hammer can be seen in the background.
The caption reads in the original French: Sur place il en fait des canons.
The color process used for this illustration falls into the chromotypograph category, which encompasses various obsolete techniques and shouldn’t be mistaken for the more current four-color process. The four color plates featured in the French edition have been left out of the copies published by J. B. Lippincott.
