This is the second of two comic variants produced by DC in 1987 with simplified cover art and a "Superman Comics" test logo (replacing the DC logo); this seems to have been a marketing experiment to see if they
could sell more comics to the younger readers via the newsstand market (which was around 30% of the total comic distribution at that time but in rapid decline).
The variants, this comic and the seemingly rarer Fury of Firestorm #61, were only distributed to select markets, including parts of California.
Below are the standard variants, both newsstand (with the barcode) and the direct edition:
There are always a few of these on auction sites such as ebay with a top graded CGC 9.8 going for just over $200 in March 2014.
In late April 2014, CGC had 229 Justice League logo variants in their grading census (around 32 times more graded than the Firestorm variant).
