Good morning,
I began posting in this thread on the 6th of October 2025, so I am nearing the end of my little two County show n tell, until I add more cards and covers.
Seven for today.
Monroe,

a pair of Yosemite view cards apparently sent from Healdsburg aboard the Willits & San Fran. RPO, each with the same postmark variety!





Here are the Mobile Post Office Society's Willits & San Fran. RPO listing illustrations and the two constant varieties I have found.
Remenber that RPO postmarks are steel and anything found in or missing from is constant.

I labeled these two as I did because they looked closest to the parent U number. The variety on the above postcards stayed in use from 1904 to 1908, when it was apparently discovered and removed from circulation. U1a was a long running variety. From 1903 to Sep 30th 1914 so far...
Hardy,

Melburne, no day date, but Oct 1908,

Point Arena,

and Beatrice,
