Stephen and Glynis Woolner first sent the cards in 1978.
They packed the card away with the decorations and came across them the following year.
Stephen decided to give it to Glynis again as a joke. She decided to do the same and now they do it every year.
Each year they write a new message on the card.
Glynis told The Sun: "We are going to have to glue a sheet of paper in so we can carry on.
"Friends come round and say 'Not those old cards again', but we love it. If he bought me a brand new card now I wouldn't accept it." (The Sun)
