Bad Taste/Fistful of Fingers

so I've been trying veeery badly to find this on VHS to watch, since Edgar is one of my favorite filmmakers...and whilst browsing the nets I noticed that the box art is very similar to that of peter Jackson's debut film Bad Taste: It shows a cowboy giving the finger, whereas Bad Taste shows an alien giving the finger. Coincidence? Evidence of PJ's influence on Edgar (or at least on the film's marketing team/art department)? I mean, he has acknowledged his love of Braindead...any other thoughts?
