From the USPCC ( I hope I'm not violating any copyright laws)Text above S64 is continuation from below.
It would seem from above info all the ads were printed by G.E.before the rate increase was authorized and surcharge was added ( by PO permission) to the 750k printed by G.E..
As such,while interesting, isn't really a color missing issue in relation to the S64 GE surcharge, but would sure spice up a specalized display of the GE authorized surcharge.
P.S.- the cards appear to be from two different "ETR"runs.
P.P.S - I'm no expert, so I could be over my head here.
P.P.P.S.- Still would like to see the front of the cards
Best to all,
