Before Black Widow was delayed and San Diego Comic Con was cancelled, LEGO Marvel 77905 Taskmaster’s Ambush was intended to be an event exclusive set. Instead, the set is available for US fans at LEGO.com.
Here is the official product description:
Superhero fans can capture the Marvel movie action in a play-and-display model depicting Black Widow and Red Guardian as they take on the super villain Taskmaster in his 6-wheel monster truck. The 3 collectible minifigures carry a range of weapons, including batons, shields, sword and a bow and arrow. There’s also a safe box and other accessories to inspire endless imaginative adventures based on the Black Widow movie. The completed model will add a great conversation piece to any room.
The box art has a comic book style to it and features the name of the event, San Diego Comic Con, that it was intended for.
