DC Comics Presents, Vol. 2 exists in the database & seems to include the correct bar code references, and they are all numbered as #1 (which is the correct number on each of the comics’ indicia). However, the descriptions are all for the same comic (the Superman issue), which is incorrect.
I’m not sure how you want to correct this, you could either update each of the descriptions in the current listings to match the relevant comics, or (as I would prefer) re-list them, as http://dc.fandom.com (DC Comics Presents (2004—2004) | DC Database | Fandom) have done (as separate one-shots);
- DC Comics Presents: Atom #1
- DC Comics Presents: Batman #1
- DC Comics Presents: Flash #1
- DC Comics Presents: Green Lantern #1
- DC Comics Presents: Hawkman #1
- DC Comics Presents: Justice League of America #1
- DC Comics Presents: Mystery in Space #1
- DC Comics Presents: Superman #1
All of the images and correct descriptions are available in the links above.
