Fascinating papers found amongst a cache of documents belonging to Earl C. Hansen, a California inventor (Vacuphone hearing aid and early wireless radio technology).
This letter is signed Oliver (from other documents not included in this sale, we have learned this is Oliver P Adams) sent to Mr Brant (which we know is O F Brant of Title Insurance & Trust Company), discussing the Peace Treaty Patent Convention and attempts to sell his apparatus to companies including Western Electric.
Cool piece!
Wear commensurate to age, including, possibly, chipping at edges, folds, and other minor issues. You get what you see :)
