Speculation is probably from the fact that there've been a half dozen or so Keyper images posted by Richard Breese in the page for Key Market.
My guess is that was an accident, but I can see how that would lead to thinking Keyper is connected to Key Market by more than just being in the Key series.
Correct. Apologies for the confusion. I wanted to post a new Key Series image and added an image for the Key Market cover. I must have left that page open when posting the Keyper images. Hopefully all sorted now and images re-posted under Keyper. Thanks for your vigilance.
