Here is the cover from the letter above.


During the 1884 thru 1891 period, the USPOD sometimes used a 'Letter returned to the Office by Carrier' label typically for one of several reasons such as;
- when the address on the letter was incorrect or incomplete
- when the addressee had moved without forwarding info
- when the addressee refused to accept the mail item
Based upon my limited discovery, these labels appear to be used by the larger Post Offices. I have only recorded usages from New York, Philadelphia, Boston and Sacramento in either a yellow or white background.
While you can occasionally find mint labels for sale in the <$15 range, the covers often command fairly high prices.
