The registiy of the Rio Grande is actually wrong on that cover if you look closely; it uses the registry of the Shenandoah (NCC-73024) from "Change of Heart" and "Valiant".
I'm sure Doug Drexler will whip himself naked through the streets of Aberdeen while weeping bitter tears of regret.
Just kidding. Apparently, the registry-number error in the digital model of the Rio Grande
is a holdover from the post-production files of the DS9 episode "Treachery, Faith, and the Great River."
Ah, well. Bummer.
