I like to collect ... books too. This is why I got the premium version... there is also numbered/signed version (100 items)
below I am attaching the explanation they give on the seller's website, but there is also a note on the book itself.
I will send you a photo of the page in question...
ERROR NOTE: This 'Premium' book (which uses superior ink) contains a set of memorable ERRORS including a random vacation photo swapped with that of a coin. These were fixed in the updated version but these 'Premium' books remain on sale as collectibles for now but will later be discontinued. The 'Encyclopedia of Physical Bitcoins and Crypto-Currencies, Revised Edition' is both cheaper and error-free.
I also bought
"obtorto collo" on amazon but it was the only plausible option (and I also had a series of coupons to spend ...) I have never seen people selling their copy on forum...
