The Queen's Gambit has received critical acclaim ever since its debut on Netflix. However, one tiny detail has blown comic book fans' minds -- and not in a good way.

Comic letterer Pat Brosseau posted an image from the show on Twitter when chess prodigy Elizabeth Harmon visits a drugstore. The spinner rack in the store caught Brosseau's attention, as it was full of comics that were two decades ahead of the show's 1963 setting.

He wrote, "This scene is supposed to take place in 1963 but I see Avengers, Deathstroke and Spider-man comics from the 80s and 90s there!"

Among the comics on the rack are issues of Peter Parker, The Spectacular Spider-Man and Star-Brand, both of which were released in 1976 and 1987 respectively. Fans expressed shock at the flub, including actor and avid comic fan/writer Patton Oswalt. "STARTING A CLASS LAWSUIT ACTION NOW," Oswalt replied.

The Queen's Gambit is based on the 1983 novel of the same name by Walter Tevis and stars Anna Taylor-Joy as Elizabeth Harmon. The series is also written and directed by Scott Frank, who contributed to the screenplay for Logan. Frank also created the Western drama Godless for Netflix, which focuses on outlaw Roy Goode (Jack O'Connell).

Streaming now on Netflix, Queen's Gambit stars Anya Taylor-Joy, Isla Johnson, Bill Camp, Moses Ingram, Christiane Seidel, Rebecca Root, Chloe Pirrie, Akemnji Ndifornyn, Marielle Heller, Harry Melling, Patrick Kennedy, Jacob Fortune-Lloyd, Thomas Brodie-Sangster, and Marcin Dorocinski.
