This complete four-volume encyclopedia, edited by Bernard E. Jones and published by Waverley Book Company, is a definitive early 20th-century guide to manual crafts and home engineering. Extensively illustrated, it covers a vast array of skills from woodworking and metalwork to period-specific domestic repairs, making it a valuable resource for historians of technology and traditional DIY enthusiasts alike. The set is in fair vintage condition, featuring shelf wear, frayed spine ends, and bumping to the red cloth boards; internally, the bindings remain generally secure with expected tanning and foxing to the pages consistent with age.
