It actually adds to the interest. Some people specifically collect mis-registered covers.
A mis-registered double cover may be close to unique, especially in this grade. (I certainly cant think of another.)
Plus this copy has beautiful colors, which all of us FH geeks highly prize.
Extraordinary book!
Thanks for the comments. I absolutely adore the book, and it has quickly rose to the top of my collection as one of my favorites. The colors are incredible in hand and then you open it up and see the interior cover..it is incredible.
My copy of Planet 48 is faded but in register but I still don't like it as much as Planet 22 (next to 48 in the bottom row) which is a little beat up.
