Just got this in the mail.
A 1924 May 9 registered cover which went unclaimed (refused, actually) and was returned to sender.
The "unclaimed" appears be be part of the pointing fingers stamp as it's so well aligned.. There is at least one similar in the database already which is also a 1924. The strike on this one is so poor that it would be hard to distinguish, but I offer it as an example from Pennsylvania, would have been struck in Sharon Hill to be specific.
The stamp is a perf 11 Sc. 510. The envelope is perhaps a die 1 U430 amber, unless it is a badly faded U429 white. (I am not an envelope guy except for air-stationery.)
