Where on the Web can I find Genesis/MD cover scans?

Last week I bought a second hand Ranger-X, PAL edition, but both the cover and the manual were missing. Fortunately, the cartridge itself is ok.

The black box is looking particularly pitiful, considering the kick-ass mecha shooter cartridge it hosts.

Anyone knows where I can get a decent cover scan so that I can dress the poor thing? Thanks to those who will answer my plea.
