This car uses the "Super Van" casting, originally designed by Larry Wood. The graphics were inspired by the Marvel Comics character, The Incredible Hulk.
This version was released in 1979 as part of the "Heroes" sub-series. Model 2878 with Blackwall (BW) wheels is from that release.
This is a licensed character vehicle. The van is painted bright green and features large, colorful comic book-style graphics of The Incredible Hulk on its sides.
This is a variation of the ubiquitous "Super Van" casting, which has been used for hundreds of different promotional and character releases. It is similar to other Marvel superhero vans released at the same time, like the Spider-Man van.
The primary variation for this model is the quality and placement of the side tampos.
