Thanks R.Coltrane for your help with getting better pics of this artwork and your advice! While these won't replace high quality photos or scans, I was able to use them to get a much closer approximation of the original artwork. I combined images from multiple sources to create these and they are not 100% authentic.
So, I'm putting these out here as placeholders for anyone wanting this art until we can find better scans.
