This book is from 1977 and only the interior pages show some yellow. The cover and edges look like new. It has two illustrated stories.  on page 2 starts The Return of the Metamorph and page 15 Queen Brain. The author is Mary A. Mintzer and the illustrator is Frank Bolle.

It looks in great shape and minor wear at all.

If you have any questions please ask them first.

Thanks for looking
