The 3rd UK format by Redwing Library

I'll admit, I haven't had much interest in this format until now.  And even now, I don't have much interest in it  =)  I've been told that these are not bound that well, so finding copies in good shape can be difficult.  I now own 4 of them, so some pictures below are scans of those. 

I believe these are from the late 1970s, but am not certain about that.  I also don't know the numbering sequence for this format, so these are not in any particular order below. 

Some of these cover illustrations really are nice!  I like Blueberry Island and Meadow Brook.  Maybe I will eventually start collecting this format, too. 

Thanks to Jim McNamara, I have some scans of the back covers of several of the books below.
