Giant-Size Avengers #1 is a giant-sized, square bound book with new stories.  It features the 1st appearance of Nuklo and the 2nd appearance of the Invaders.  It sports a killer John Romita cover and Roy Thomas story.  This book is graded 9.8 NM/MT with white pages by CGC.  The spine is nice and square.  Alignment is perfect.  Sorry for the scanner glare...it is not a book defect!  A pretty rare book in this high grade...there are only 40 9.8's in the CGC census.
