I was disappointed that Yosemite — one of my favorite parks — was not one of the sixteen featured in the National Park Service Centennial issue. When Americover offered a centennial with a Yosemite pictorial postmark, I took the opportunity to create a Yosemite cachet to match my first day covers for Scott #5080.
For these covers from @McGeekiest Cachets, I used one California flag coil single from Flags of Our Nation (Scott #4279) and one National Park Service Semicentennial stamp from 1966 (Scott #1314). The cachet matches the design for the 5080 FDCs: a photograph taken in the park, warped into a sphere, with a green trace behind it that makes a right-angle turn and ends in a stone arrowhead. Above the line, the name of the park is printed in a chiseled stone font.
The stamps are canceled with an Americover Station "Yosemite" pictorial postmark from Falls Church, Virginia, 22042, dated August 19, 2016.
