This is a good antique L&JG Stickley large armchair from the Onondaga Shops period in very good condition.
The piece has early, bulky form with 1.25 inch thick arms.
It is made of quarter sawn oak and has an old refinish.
The arms have through tenons and the chair is pinned at the front.
The upholstery has been redone with very thick, high quality leather using original large round brass tacks.
This is an unusual, collectible piece.
There are some possible label remnants as pictured
