It never ceases to amaze me what questions get asked here at Google
Answers, and what obscurely wonderful tidbits of information research
will sometimes turn up.
Dr. Brown's has long been a New York City staple, especially in the
Jewish community. It's been around for more than 125 years.
You can read a bit about it at this brief Wikipedia entry:
But the label images for Dr Brown's are a fairly recent addition to
the line. In fact, the carousel is the most recent of all the label
images, and thus has no real relation to the original founder of Dr.
In the 1970's, as part of it's affiliation with the city, the labels
on Dr Brown's sodas were adorned with old prints of NYC icons. The
original sodas bore the following images:
Statue of Liberty -- Cream Soda
Brooklyn Bridge -- Cel-Ray
Grand Central Station -- Orange Soda
A NYC Ice Cream Parlor -- Root Beer
Astor Hotel -- Ginger Ale
3rd Ave El Train -- Black Cherry Soda
As Dr Brown's expanded to out-of-town markets, marketing types thought
the 3rd Ave elevated train was deemed a bit too obscure for non-New
Yorkers, and the image was changed to the Central Park Carousel.
