A Real Life Black Bob Mystery!

The other day I picked up my first Black Bob annual - the 1961 book to be precise. However, there seems to be a bot of a problem with it - and not just a small one either. No, instead - one of the stories has been printed twice! Black Bob and the Shepherd Crook started on page 33, and what should be page 97!

Where the story should be.

After the second Sheperd Crook story the pages numbers go 45, 46, 47, 113 and correctly from there!

The same story - but on page 97!

Is this a one off mistake or did lots of these books have the same mistake? (I know not all of them did as I lookeed at the contents of another copy online). And if this is a one off mistake - how did it occur? It's a pretty big printing error and yet the book was still distributed.

Take a look at the page numbers here!
