Newbie here w/inherited. Looks like my grandfather went to great length to collect as many RPO's cancellations as possible. Probably 200 different covers maybe more. Mostly northeastern routes, mostly 1920's and 30's. Is there any interest in these anymore? I know first day covers are more widely collected. Is this even the forum that would discuss this?
Thanks in advance. JoJo*** Moved by Staff to a more appropriate forum. ***
