The 'Agatha All Along' line includes numerous products featuring Bewitched-esque artwork of the character, including t-shirts, hoodies, socks, cups, mugs, bottles, phone cases, tote bags, a cap, a headband and a mousepad. These items are available through multiple online retailers like Amazon, Zazzle, Rock 'Em Socks and Junk Brands.

Created by Stan Lee and Jack Kirby, Agatha Harkness first appeared in 1970's Fantastic Four #94. In Marvel Comics canon, Agatha is a skilled witch who survived the Salem Witch Trials and went on to mentor none other than the Scarlet Witch herself, Wanda Maximoff. WandaVision's seventh episode, "Breaking the Fourth Wall," debuted on Feb. 19. In it, it is revealed that Wanda and Vision's nosy neighbor Agnes, played by Kathryn Hahn, is actually Agatha -- and that she's the one who's been causing all the problems in Westview. She makes this clear with her song "Agatha All Along," which was recently made available on music streaming platforms like Spotify and Apple Music.
