Marvel mastermind Stan Lee has cancelled a scheduled comic convention appearance due to ill health.
The 94-year-old was set to appear at the Big Apple Comic Con in New York this weekend (local time), but pulled out at the last minute.
In a post on Instagram, the convention said Lee "keeps to an amazing schedule and it seems to have taken its toll".
"Let's all wish Stan well and party like you know he wants us to."
It isn't the first time the legendary comic book writer has cancelled an appearance, though always makes it up to fans when his health improves.
During his decades-long career, Lee created hundreds of much-loved superheroes and villains including Spider-Man, Black Panther, Black Bolt, Daredevil , The Incredible Hulk and X-Men's Magneto.
He also makes cameo appearances in all of Marvel Studio's films.
