1857 Rochester, NY Cover Brought Home From UK

For a couple of bucks, I've brought this cover full circle. Originally sent from Reading Pa. to Rochester, NY. Somehow it found it's way to the UK. Now it's back in Rochester.

The Arcade Gallery address I believe, is the Reynolds Arcade building. That building has some nice history. Most notably it was the birthplace of Western Union in 1856.

I can't read the writing over the stamp top left. Would that be the Postmaster?

Mr. Barclay was not Postmaster in Reading; this is not a Postmaster manuscript cancellation. George S. Barclay was listed as an Attorney in Reading, Pa. from 1848-50. The marking over the stamp refers to a case: Cheny vs. Griffith. In the 1850's, Pennsylvania judicial system grouped counties into judicial districts placing president judges at the head of the District Common Pleas Courts; Reading, Pa. was the center of one these districts. Attroney's travelled for miles (sometimes days) to plead cases before this court. Your cover refers to a case (Cheny vs. Griffiths?) pleaded by George S. Barclay, an Attorney -- not a Postmaster. Barclay may have been from Chester, Pa.

YES! that makes sense. The squiggly line between the two names is the vs.
Thanks Hal

It amazes me that this stamp cost ten cents in 1857 and it would cost seventy five cents today due to inflation.

It looks like a three cent stamp from here.
