Stamps On Envelopes

Hello, friends!
These stamps on envelopes may be of interest?

NICE! Looks like a Scott #65 with a cork "fancy" cancel (circle of wedges) from OLD POINT, VA. and the next looks to be a Scott #U15 postal stationery with the Carson City cancel very neat! and the last one looks to be a #26 with a manuscript type cancel in a grid fashion or just a cork fancy cancellation that wasn't well struck but it's on an all-over advertisement cover. I would like to see the whole cover if you don't mind? Nice stuff! -Jeff

The first postmark is from Old Point Comfort, VA. The now discontinued post office was in operation from 1824-1880.

The second postmark is from Carson City, Nev. T. (Nevada Territory) which was obviously before Nevada became a State in 1864.

Thank you, folks!

The London cover from Dr. Barnardo's Homes has an interesting history:

Bummer about the condition of the 2nd one. As wt1 mentioned it's Nevada territory, it's a U40 (I think) Stamped envelope, catalog value $60 and a nice crisp Carson City CDS so it has some nice features but condition is poor.

Thank you! Very good information about Dr. Barnardo's Homes.
