Instructions and list of eight offices at left, unusual square grid cancel, addressed to "Adams & Co." at corner of Merchant and Montgomery in San Francisco, some wear incl. creasing, otherwise Very Fine, genuinely used examples of this entire are extremely rare (remainders were used to create forged Wells Fargo express usages), one of the fascinating aspects of this issue is that both the Penny Post oval and 3c U.S. stamp were embossed in the same color by George F. Nesbitt, ex Golden and Geisler, with 1967 and 2009 P.F. certificates
