There is a glitch on comicbookdb mainpage. Guardians of the Galaxy (1990) #3 appears twice at the same time
(as a "Past DC/Marvel Book of the Day"
AND a "Past TPB/Hardcover of the Day")
Not sure why it is a "TPB/Hardcover of the Day", since the issue webpage says the published format is "Standard Comic Issue".
For some reason the User Rating is different, but both covers link to the same issue ( http://www.comicbookdb.com/issue.php?ID=29429
