There isn't much variety in Jaguar boxes. Nearly all Jaguar games were released in cartridge form, and all the boxes we've seen thus far (which is most of them!) use a nearly identical box format. They're all the same size, have a black background, feature the Jaguar logo and the text "Interactive Multimedia Cartridge", and feature a single screenshot in the lower-left corner of the box front. The biggest difference in packaging comes from CD games vs. cartridge games. Most CD-based games were delivered in cartridge-style boxes that were a touch taller than their cartridge counterparts. The CD games packed in with the Jaguar (Blue Lightning and Vid Grid) used smaller, cardboard packaging that folds out to reveal the CD.
It's generally easier to find Jaguar games boxed since the system is fairly young, at least relative to Atari's older systems. In addition, vendors are still selling new, boxed Jaguar games today.
