Royal Mail delays reached new heights when a Crystal Palace man received a letter 100 years late.
Theatre director Finlay Glen, 27, of Hamlet Road, was “mystified” when the overdue correspondence dropped through his letterbox in February.
Written in 1916 – around the time of the Battle of the Somme – it bore a George V stamp.
Local historian Stephen Oxford gave the tardy treasure his seal of approval – saying it shed “new light” on the neighbourhood’s Georgian families.
Postal punctuality is a regular problem for local residents who believe it had sat in a dark corner of the Sydenham sorting office for over a century.
The letter garnered international attention, with news of its late arrival being reported in Argentina.
A Royal Mail spokesperson said: “Incidents like this happen very occasionally, and we are uncertain what happened in this instance.”
