Hey Berwyn,
GREAT NEWS. I prefer the more RIBBON style lettering as shown in the IRM photo you posted. I will wait to see the art work before I order my sets, especially for the baggage and RPO. As a thought, how about offering the RPO and Baggage without numbers as well and include matching numbers. This way, I can build my full set of mail trains that the Q ran in the 1950's and 1960's with multiple RPO's, Baggage, and REA express cars.
