This is a very special and extremely rare CD-ROM. 

Issued in 2002 to promote the album "The Ragpicker's Dream. Some of the contents are: 

.eps file with the Mercury logo in different sizes, big poster picture, several fonts, banners etc. Most likely used to create promotional posters, ads and similar material. There are still some filetypes on the CD that are still unknown to me. They have no file format set, and are just referred to as a "File". If the remaining files get known I will post info about them too. Below are pictures of cover/CD, and printscreens from some of the files.
