Readers might assume that a Facebook page called "Pictures in History" exclusively shares photographs documenting historical events and facts. However, that account frequently posts miscaptioned or outright doctored images.
This image was not a genuine photograph of a quintuple skull, but rather five individual skulls blended together with photo-editing software.
This picture can be traced to December 2006, when it was shared on Flickr by Richard Kittel along with a piece of text supposedly explaining the backstory of this unique cranium. The backstory, of course, was just as fake as the photograph and included a number of unbelievably outlandish claims. For instance, Kittel wrote that the quintuplet born with this unusual skull lived in a closet for 41 years, spent three weeks in coma after he failed to turn sideways while walking through the door of a candy store, was blind in two of his six eyes from a BB gun accident, and that his skull went missing after his funeral, only to turn up years later in a drug bust after it was re-purposed as a bong.
In addition to the ludicrous nature of this skull's alleged history, Kittel also noted in the comments section that a "little photoshop was involved" in the creation of the image:
A number of doctored skull pictures can be found on Kittel's Flickr page. In fact, a few days before he posted this "Quintuple Skull," he shared a slightly more believable image of "fused heads," which featured two of the skulls seen in the above-displayed viral image. Kittel explained in that post that the image was "whipped up in Photoshop using images of actual human skulls offered for sale on eBay":
