This is a new discovery for me, an edition of the Big Golden Book from Spain! This is from the Coleccion Galas Infantiles - which loosely translates to Child Gala Collection.
There are several differences in this book from most of the other editions of the BGB. First, it is soft cover rather than hard cover. Next, it is approximately half the size of the standard BGB. Third, it uses new and different cover art. And finally, the pages are not in correct story order. I originally thought that it might have been assembled incorrectly, but in fact not, as the pages are printed out of order.
Stay tuned, as we'll see this cover art again.
