What is the oldest cigar you have ever smoked?

I have been quite fortunate as well.

I have smoked a 1973 Flor De Cano a 1968 Upmann

I have in my posession a 1950's White Owl that is very special

I also have another 1960's pre embargo Clear as well as a foil wrapped cigar that is apparently from the 1930's to 1940's

I hope to smoke some of my own that will be 40 plus years old..............but that means I have to make it to 75 years old to do it...........I am planning on it but who knows.
