In the first main area right at the start of Sentinel Site Prescott, in one of the outer hallway areas, under some stairs, this magazine is found on the desk as part of a large row of work terminals on the eastern side of the facility.
Astoundingly Awesome 10: Gain +5 Radiation Resistance.
The perk provided by Astoundingly Awesome Tales #06 is ambiguous in its description that it heals the player one point per minute. Health is restored at 1 point per in-game minute.
However, this is taken into account by the Waiting system in the game, healing the player character by the amount that would have been healed if they had actually spent the entire in-game hour playing.
Looking at the game's files, it would seem that the perk for issue #09 does nothing. However, there is actually a hidden 15th perk, PerkMagAwesomeTalesDogmeat "Astoundingly Awesome 15" [PERK:00169693], which Dogmeat has from the beginning. It is inactive until player.HasPerk 169692 is true, which is to say his human friend has picked up issue #09 and received its perk. When that condition is satisfied, Dogmeat's own perk will activate, removing 10% of his incoming weapon damage.
On the cover of issue 14, the license plate reads "4LL-0WT-4" and "Bethesda MD" referencing the name Fallout 4 and Bethesda, Maryland, the original home of Bethesda Game Studios.
The man who could stop time is also a play on the fact that the player can effectively stop time when using V.A.T.S., hence the additional action points.
The title "Have Dog, Will Travel!" is modeled after a phrase made popular by Have Gun – Will Travel, an American tv and radio western that ran 1957-1963 (1958-1960 for radio) featuring Paladin.
The following is based on unverified behind the scenes information and has not been confirmed by canon sources.
The man who could stop time may be in reference to an episode of The Twilight Zone, where a man is given a stopwatch, which stops time, he then uses it for cheap party tricks, then escalates to robbing a bank, where he breaks it, and time is now permanently stopped.
