GB 1870 Scarce "Too Late" CDS on 1d Pink De La Rue Stationery. Sealed. Handwritten Message on rear.

The "TOO LATE" incorporated into the top arc of the cancellation dial is a scarcer type of GPO integrated late-mail marking. It indicates the letter was handed in or posted after the standard evening 6:00 PM postal collection deadline for the overnight mails at the London Chief Office/E.C. branch, but was processed under the late fee/late-posting protocol for evening dispatch.
