Three Thunder Valley Chatto covers

Thunder Valley originally appeared in MV Features' Western Trail Picture Library #7:

The cover image was swiped by Keith Chatto for Page Publications' own edition of Western Trail Picture Library #1:

Page Publications recycled this story at least two more times, under new Chatto covers. The issues I have to hand are Maverick Western Library #2:

and Real Western Library #44:

No doubt more Page Publications editions will turn up.
