Which edition of The Last Hero to buy?

Hello everyone. I'm slowly completing my Discworld collection (only 6 to go XD). And I would love your help guiding me if there's a better version of The Last Hero.

It seems to me this one is different from the others as it's heavily illustrated and not just text. Searching online I was able to find two very different covers for the same book. Are they the same inside? Would you recommend one over the other?

I'm leaning toward option A because it seems a more recent edition and I prefer the cover.

Thank you :)
