Those "cocktail tickets" are from Continental Airlines, 1960s-70s. My aunt was a flight attendant who, happily for me, saved everything. And since, as far as I'm concerned, everything is fair game in the ornament department, they now live on the tree!
More trees coming soon! And I'd love to see yours!
*Actually, this is only one of our cocktail trees. We have two others, to be featured soon. ;)
