Though just a dozen or so different subjects have been reported from this interesting illustrated postcard issue it is likely that more exist.  With no more than a handful graded, the cards are extremely desirable.  The issue is rare enough that the grading companies have not standardized the method of listing the cards so population reports for both PSA and SGC are difficult to discern.  This example is in apparent GOOD condition with some toning and wear at the edges, and light staining along the bottom.
