Much has been made of a recent tweet from Stan Lee's Twitter account showing himself, his current representative and movie producer Keya Morgan, and actor John Travolta.
It indicates an active Stan Lee and may reassure concerns from those regarding his health, and who have made those concerns known. Including friends and colleagues including Neal Adams, Mark Waid, Humberto Ramos, Peter David, J. Scott Campbell and more, especially fans attending signing sessions.
However, the photo in the tweet question was actually two years old — and was originally posted by Keya Morgan himself on Twitter in 2016.
Which doesn't mean Stan Lee isn't dancing the night away with John Travolta. But you couldn't be sure from the photo alone.
