Hardwood Artist's Easel.
This easel is gear driven in the French style, fully adjustable, and can cost you less than almost any adjustable easel you can buy.
It can accommodate canvases from the smallest up to 4 feet high - higher if the top retainer is removed and the frame tilted.
A single turn of the handle raises or lowers the tray 6 inches.
Four pages ( 3 sheets - front on the first and third sheet and front and back on second sheet. ) B & W photos, illustrations, expanded view and instructional narrative.
My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
