As we get ready to celebrate 87 years of the Macy's Thanksgiving Day Parade, let’s take a moment to reflect on its creepiest characters.

While more than 3.5 million people in New York and 50 million people at home will tune in on Thursday morning to see this year’s giant balloons, earlier parades had humbler beginnings. Called “The Christmas Parade,” the Thanksgiving event was organized and performed by only Macy’s employees.

The first balloon, an inflated Felix the Cat, was introduced into the parade in 1927. After that, balloons became a yearly tradition. At the end of each parade the giant helium-filled characters were released into the air to float over New York for roughly a week and a $100 prize was given to whoever retrieved a deflated balloon.

According to digital magazine The Wire, another forgotten fact from the parade is that the balloons used to be extremely creepy.

“The creepiness appears to have peaked in the mid-1930s, about a decade after the parade first began,” read the magazine.

Here is only a small selection of photos of creepy, floating characters. To see more, make sure to scroll through the New York Public Library’s full collection.
