This book is clearly a bootleg because: 1) it's size, 2) quality of the cover image, 3) inner text is obviously a high-quality photocopy not offset-printed.
It is a bootleg of the 10th print in 2001 and so those are the details recorded; however those are meaningless and most likely the book was created in the Americas somewhere, not in Spain.
It can be assumed, however, that the text has been faithfully duplicated.
