Cover by James Meese
Prather was also the creator of the Shell Scott series (FYI: There will be more on this subject when we start working our way through this pile) and, in fact, some sources - namely his Wikipedia page - count this as part of the Scott series. Although, from what I can tell, it's not. As the main character's name is Mark Logan.
Either way, thanks to UKVintage's photostream I learned the artwork was used not once, not twice, not thrice but... quadrice? Honestly I don't what (if anything) rhyming comes after thrice but, suffice it to say, the piece was used four times. (See here, here and here.)
As someone already pointed in out the comments in said photostream, hopefully Meese got to collect multiple paychecks!
(PS: Meese's work has previously been featured in the PFP as well, here.)
(PPS: As always, larger versions, as well as covers of books that have found their way on to the blog previously, can be seen in the Pulp Fiction Project set in my Flickr photostream, here.)
