Following a pair of reveals early in the weekend, a third "Legends of Tomorrow" teaser has been posted to the DC Comics Instagram account. Like the previous two images, this one features an iconic item from the larger DC Comics mythos. When a filter is applied to the image, comic book art and the name of the item are revealed.

The previous images featured Ma Hunkel's pot helmet and Hourman's hourglass. The latest one focuses on the Golden Age Sandman Wesley Dodd's gas mask.

Criminals beware--this mystery man goes against the grain, and he won't hesitate to put you to sleep before you strike. Screenshot this image and use filters to reveal the answer, and share your findings with #LoTEasterEggs! @cw_legendsoftomorrow: Thursday at 8/7c on The CW.

Like the other items, it's likely that you can spot the gas mask somewhere in Rip Hunter's ship, the Waverider. Whether or not Sandman or the other alluded to heroes will ever appear on the show remains to be seen. "Legends of Tomorrow" features a group of disparate heroes thrown together by Hunter for a time-traveling mission against the immortal villain Vandal Savage.

The show's already traveled to 1975 and has stops to make in the 1980s, the year 2046, the late 1950s and the Old West. Considering the nature of the show, appearances by Golden Age heroes like Sandman are plausible.

"Legends of Tomorrow" stars Arthur Darvill, Caity Lotz, Ciara Renee, Brandon Routh, Franz Drameh, Victor Garber, Wentworth Miller, Dominic Purcell, and airs Thursdays on The CW at 8 p.m.
