Looking for a place to start.

2. You could always check the corners. Sometimes a mess gets left in the corners

so that leads me to the bottom right corner.

the cipher i can make out gives me

MKH ZYMEZH

(the last H is questionable because it's on the edge of the triangle. i also just noticed the first letter could just as easily be N)

i tried shifting and didn't get anything out of it.

4. The four corner triangles of the book cover can be cut in half and rejoined. I can form three diamonds made of two triangles each, but the other two don't seem to match. The red part is at a point by the key ring and joins to a section where it gradually becomes wider. Maybe it is a path to follow to find the key(s) which belong on the key ring. On one piece is a very tiny N (or Z). The word "maps" and the line beside the letter make me favour it being an N for North.

The blue triangle in the bottom right hand corner has the parts of two symbols above the part that corgi has made suggestions for. There is no way yet of determining whether the longest side is up or down. MKH could be BQO

The smaller blue triangle in the bottom right hand corner has different shading. It is the size of the 8 triangles from the corners of the cover of the book. There is another dark grey triangle of the same size in that corner, and two other small size triangles in the top right hand corner.

5. After looking more closely at the corners of the book I think that the original 4 triangular pieces can be further divided. I'm working with scissors and paper here. I cut each of the 4 corner triangles in half to have 8 smaller triangles. Then each of those smaller triangles was divided into 2 pieces - a triangle cut off from one corner and a trapezium shape (trapezoid). That made an set of 16 tiny pieces - which I have found too small for me to manipulate. Perhaps someone with Photoshop may be able to reassemble them.

Coming late to the party here. Sorry, knocka, I don't have Photoshop. But I do have some skill in moving pixels around in Paint (I get practice when I dress the sluggy ).

Not as pretty as Photoshop but here are the pieces from the corners of the center sheet assembled:

7. Great Paint pixelating skills, Sluggy!

8. beautiful job sluggy, thank you.

Thank you sslug for sharing your skills.
I suspect there will be more times for reassembling jigsaw pieces, but they will probably be a little bigger.

10. Omg....it's Caturday!!!!!

Has cthree already found what we are looking for and posted it here?
