Here is a poster for Sonic Gems.
Gems was the 9 older games compilation released for the PS2 and the Gamecube. This poster is a little busier than others but still has eye-catching art. It has a Sonic vs Metal Sonic theme, with a good big graphic of both of them. The headline separates them. The square is the release date & the title sits (appropriatly) over an emerald graphic. There are many screen shots along the bottom, to show you which games are included. The blue band appears to have a bunch of other info too.
