That is a very cool decal, Brian.
So, the yellow circle... and T, I wonder what the globe and anchor decal looked like back then and also wonder if it was inverted like the OFFICIAL ones I have photos of.
Did we ever do anything on that decal?
Oh, history:
In the early ‘40s, both the Army and the Marine Corps were looking for land for a large training base. The Army lost interest in the project, but in April of 1942 it was announced that the rancho was about to be transformed into the largest Marine Corps base in the country. It was named for Major General Joseph H. Pendleton who had long advocated the establishment of a West Coast training base. After five months of furious building activity, the 9th Marine Regiment marched from Camp Elliot in San Diego to Camp Pendleton to be the first troops to occupy the new base. On Sept. 25, 1942, President Franklin D. Roosevelt arrived for the official dedication.
