Early Lumber Apron, found packed between 1923 newspapers with grocery receipts from 1906. I am assuming this apron may be from this period. Very dirty, looks like some tar like substance in spots. No tears, draw rope solid runs thru bib and knotted ends. Unable to find any info on Beaver White Rock Fibered Plaster. Beaver Fibered Board came out in 1903. Receipts will be in pocket.
