I have over 140 unique root bottles. All different brands. That’s been a nerdy, fun, and cheap hobby to look for and find them when I travel.
I also have the first Disneyland brochure when the park opened in 1955 as well as a souvenir guide book from the the same year and a large souvenir poster map of the park in 1958. All really fun to look at and see how the park has changed over the years.
