caffe verona texture
The Caffe Verona texture is a stock image photo of the now-defunct Caffe Verona coffee shop in Palo Alto, California, taken in 1993, and has since been used as a test image for 3D models. It's usually used for reflection mapping on shiny objects, but may also make other appearances, most infamously as the backdrop of the debug stage in Super Smash Bros. Melee.
Due to its usefulness for showing reflection, it may occasionally subtly appear in 2D artwork.
The original fisheye texture can be found here and the cube map used in Melee can be found here .
