Superboy #117

KG Murray's Superboy #117 was published c.November 1958:

The three main features and the Warden Willis filler were recycled in Colossal Comic #34. The Luxury Limousine of space was reprinted in Super Heroes Album #5. The Trial of Superboy was reprinted in Giant Superboy Album #13.

There is also a UK variant of this issue.

Super Adventure Comic #104

KG Murray's Super Adventure Comic #104 was published c.February 1959:

The Super-Sergeant, originally published in Superman #122, July 1958 

This issue also contains a single-page Little Pete filler strip originally published in Action Comics #242, July 1958 - and I'm pretty sure this is not the reason this issue is collectible today.

This issue also contains a two-page Warden Willis filler strip from Detective Comics #269, July 1959.

Super Adventure Comic #99

KG Murray's Super Adventure Comic #99 was published c.September 1958:

The cover is from DC Comics' Action Comics #241:

There are two main features in this issue:

The Two Worlds of Superboy, originally published in Adventure Comics #218, November 1955

The Super Key to Fort Superman appears to have been deemed the canonical beginning of the Silver Age Superman by DC Comics - it is the first story appearing in the recently published Superman: The Silver Age Omnibus #1, and was also the opening story in Showcase Presents: Superman #1. Oddly enough, both of these editions elect to feature cover art from Action Comics #242. 

The Super Key to Fort Superman also appeared in Australia in Giant Superman Album #2. The Two Worlds of Superboy also appeared in Giant Superboy Album #6.

There is also a UK variant of Super Adventure Comic #99.
