Holyoke's Veri Best Sure Fire Comics #1.
Veri Best Sure Fire Comics issue does not contain reprints, but rather inventory stories from Captain Aero Comics. Now that we (thankfully) have all of the issues of that title, I was able to look over them and didn't find any of these stories in there. In fact, I was able to determine that the Captain Aero story precedes his story in Captain Aero Comics #15 and Alias X and Hammerhead Hawley both precede their stories in Captain Aero Comics #11.
Also, I believe the contents are the same as Veri Best Sure Shot Comics. Both covers (from Heritage) are included in the upload and are identical except for the title.
