Telegraph Despatch Post Office, Philadelphia, Pennsylvania, 1c black on yellowish paper, margins ample to large, cancelled with black manuscript "X", on partial folded letter to Washington, D.C., postmarked with blue "Philadelphia 5cts" c.d.s., cover with some staining predominantly at left, adhesive with slight scuffing in margins, of little importance given the rarity of this local on cover, with 2021 Philatelic Foundation certificate; ex-Gibson, with his owner's mark on reverse.
The cover offered here is one of only three recorded in the Roth census (Penny Post, Vol 3, No. 4). A fourth has since been discovered.
