Fellow Marx fan Matthew Coniam, on his Marx Brothers Council of Britain blog has brought up the topic of Marx Brothers balloons in the Macy's Thanksgiving Day Parade.
Trolling the internet, I have found two pictures of the big-headed brothers which appeared in the 2003 parade.
From AVclub.com, I present the following excerpt from the article, “Look kids, it’s Eddie Cantor!”: 12 obscure Macy’s Thanksgiving Day Parade balloons from years past. Based on the pictures above, it seems that the article is incorrect in stating that four brothers were represented in 2003.
When four balloons representing the Marx brothers marched through the 2003 Macy’s parade, spectators may have been a little baffled. The Marx balloons were part of an attempt to celebrate the parade’s past by copying vintage designs from back when the Thanksgiving streets were filled with more than just cartoon characters and advertising mascots. They weren’t traditional balloons, but rather floats with giant balloon heads meant to resemble the brothers. The giant-headed brothers, decked out in black and white, had been a mainstay of the parade in the ’30s, but in the 21st century they came off as garish, bizarre, and vaguely horrific. They haven’t reappeared.
