The Gaslight style is a name for a particular Victorian graphic design style. In this style there is a great interest in creating the illusion of depth. Design elements are made to seem multi-layered with the use of shadows, imposition, dimensional banners and ribbons. Little detailed ornaments are used in the artworks, as well as typography.
The Gaslight style has been used for labels, packaging, signage and business stationary. The name seems to have evolved from the optical illusions created by streetlights on storefront signage. This would cause a shadow which resulted in a 3D look.
