Grand Collection is a compilation series on the "Квадро-Диск" label. It was started in the 90s - with compilations with erotic artwork, which was based on works of fantasy genre painters (such as Boris Vallejo), and in this way the design was similar to label.
However, in the beginning of the 00s series design was completely re-branded. Probably it was done because early releases had questionable legality status, while with new releases the label was working in full compliance with updated and restricted Russian copyright laws.
For Grand Collection-releases with same name but a different branding that are pirate/bootleg releases with Квадро-Диск-copyright that were released by Квадро-Диск (2), see Grand Collection (5)
