red datestamp reading "Port Angel W.T." ties 3c Rose (65) to 1863 cover to "Seattle, Puget Sound, Washington Territory", the postmaster added a manuscript "us" at the end of "Angel" in order to correct the datestamp's error, manuscript endorsement at top left reads "Via San Francisco, thence coast wise to", very fine, accompanied by a 1966 Linn's article by David Jarrett explaining both the postmark error and the nonsensical directive, since Port Angelus and Seattle are only 60 miles apart it would make no sense to route this cover through San Francisco, another cover from this same correspondence from Pennsylvania bears the same directive leading Jarrett to believe these envelopes were pre-addressed and mailed en-route to Washington Territory, very fine and unique, one of the most important Washington Territory covers in our opinion
