Bootleg?

[Tsukento]

The cover art looks professional enough, and it's not like legitimate dubs haven't mixed movie promotional art, using characters that never even appear in that film and the like. If I hadn't seen this I might not have realized it was bootleg either.

Despite whatever grievances people may have with Funimation, their movies are still the best copies of the show you'll find, next to the Japanese release of course. No bootleg can match them for film, sound, and translation quality.

If by professional you mean simply slapping a cut-out of Coola onto a basic poster for movie 9 and give a gradient glow while putting two parts of the same image on the back to cover the original DVD detail and adding the basic info of the disc while leaving the second movie's description in and covering the original logo with a Japanese Dragon Ball Z logo, then sure, that's truely as professional as they can get.

I've seen better looking bootlegs. Namely the blue covered ones with a character outlined in yellow for each case.

[Deus ex Machina]

I said "professional enough", not professional. Many dubs of the show outside of the US and Japan use shoddy cover art, mixing random cover art using basic photoshop techniques.

I didn't say they were the best i had ever seen either, only that they could be confusing. Especially now when anyone with enough skill and resources can make their own mock covers.
