Hello TheGirlHasNoName;
Adventure Comics 459-466
From issues 459-466 Adventure Comics was a 68 page, $1 book. $1.00 was pretty much the price of 3 regular comic books combined back then, as result these did not sell in great numbers. The book's also have different front cover look which in addition to the page count and price I feel separates them nicely from the rest of the run, much as the later digests do. Issue #462 in my opinion is Bronze Age minor key, albeit a sad one, as it features the Death of the GA/Earth II Batman.
Many thanks for your time, effort and consideration in fulfilling this request.
