Australian Marvel Special Edition #2: The Empire Strikes Back

This is a interesting variant of the Marvel Special Edition #2: The Empire Strikes Back.  This was printed for distribution in Australia hence the lack of price on the cover.

Marvel Special Edition #2: The Empire Strikes Back a - Marvel Comics, Australia (Spring 1980)
no price; U.K. edition?

It looks identical to the U.S. edition, except for the blank white box where the price goes.  The copy I bought came from Australia and I've seen another copy recently on eBay that was also being sold from Australia.  If you know more about this comic, I would appreciate hearing from you.
