Unusual Decorations

We have some very old decorations on our tree but one of the most unusual is this bottle of Coca-Cola.
It really did have Coke in it when I met Marlane but, over time, it dried up and we had a transparent glass bottle. Tried dribbling more Coke into it but it dried up quickly as the top was corroded.
Last year we had a go at the top, cleaned it up and sprayed it silver. The glass bottle is now spray painted with gloss black paint. It looks pretty much original and hangs on our tree each year.
I asked Marlane how old it was and she remembers it from when the family were in Cyprus, her father was stationed at an RAF base in Nicosia (Lefkosia now since the island was separated in 1974).
That was 1966 so the little bottle, about 2.5 to 3 inches high, is coming up for 53 years old.
