Paul Biggs, from Longlevens, said he was absolutely shocked when his postman arrived at his front door with the card from his friends in Bitburg in Germany.
He said: “I can’t believe it – it’s eerie – it’s just got ‘England’ and sent from a sorting office in Bitburg.”
Royal Mail said its “address detectives” were renowned but “even by their standards” it was impressive.
Mr Biggs said the card had been sent by his friends in Germany on Monday and was handed to him by his postman on Wednesday morning. The postman had been carrying the letter as he completed his round, asking his customers if the card was for them.
