A Spider-Man figure in mug form, made by Geeki Tikis.
This mug is a tikified re-imagining of this comic book character from the Marvel Comics Film Universe.
In the comics, an American teenager (Peter Parker), a poor sickly orphan, is bitten by a radioactive spider. As a result of the bite, he gains superhuman strength, speed, and agility, along with the ability to cling to walls, turning him into Spider-Man. He later teams up with the Avengers superhero team.
This mug was one in a series of "Avengers" mugs (including Thor, Hulk, Captain America, Iron Man, Doctor Strange, and Black Panther).
