1906 Hawaii understamped PPC to Sheffield with 5 centimes Tax mark
This is a picture postcard of Stanford University, San Francisco after the 1906 Earthquake, oddly used in Honolulu, Hawaii a couple of months later. It was addressed to Sheffield, endorsed "Printed Matter" but deemed understamped and charged with a very scarce T 5 CENTIMES tax mark in violet, applied at Oahu. In addition, there is the 1d F.B. English charge mark.
