The Bank Collection is a Valve-made collection of CS:GO skins introduced on 1 May 2014. The collection consists of 6 consumer skins, 5 industrial skins, 3 mil-spec skins, 1 restricted skins, 1 classified skins, and 0 covert skins.
The Bank collection skins are inspired by the demolition map of the same name. A variation of the Bank map also features in the Payday 2 videogame. Tuxedo skins are also likely inspired by the suits worn by the Payday gang. This is further reinforced by the fact that all weapons in this collection are not CT-exclusive.
The R8 Revolver Bone Mask skin was added to the collection nearly two years later on 8 December 2015.
