While it at first looks like a first edition, this is a reprint. It has a different barcode, and is missing the catalog number from the first edition both on the back cover and on the discs. The discs are all in the same hue (the difference in the scans below is due to the discs being scanned by different people), unlike the first edition disc labels which are in three slightly different hues (like all European first editions).
3. Disc 1
4. Disc 2
5. Disc 3
