Vintage Ladder Types - Historical Illustration of Wooden Ladder Designs #3094247 (License: Personal Use)

This black-and-white technical illustration depicts four traditional wooden ladders, each representing a different functional design from the late 19th or early 20th century. The leftmost ladder is a tall extension ladder with a rope-and-pulley mechanism; next to it is another extension ladder with a simpler locking rung system. The third is a plain straight ladder, while the rightmost is a tapered step ladder with reinforced side rails and rungs. All feature hand-drawn precision, suggesting use in manuals, catalogs, or engineering references.
