Issue One printings
I'm a bit uncertain about the printing history, but here's my take:
* "Premiere Issue" - Gray-colored cover, digest-size (unlike all the UO mags that would follow). Winter 1990. Pictured above. I've only seen one of these thus far, so the premiere issue is quite rare.
* Orange cover - Wider-format, almost a square. 2nd printing (assumed, not stated), December 1990.
* Orange cover - 3rd printing, April 1991. Otherwise identical to 2nd print.

Unspeakable Oath - Issue 5 (Call of Cthulhu)
"Feeling hunted? Do people persecute you because you're somehow...different? Just because you have gills on your neck and wear spooky t-shirts? Then come with us to the Emerald Isles, Great Britain, the United Kingdom, and all that jolly rot. This, you see, is the British Issue of The Unspeakable Oath, chock-a-block full of articles and scenarios for Call of Cthulhu gaming in the U.K. There's so much cool stuff in here we can't begin to summarize it all, but just for starters you'll find: ley lines, a disease that turns your blood to jelly, ancient monoliths, friendly pubs, a spectral hound, and the biggest, nastiest monster this side of the Great Old Ones. Got your interest? Then get hooked. Stop feeling like a fish out of water. Devour The Unspeakable Oath - then cross your heart and hope to die."

Unspeakable Oath - Issue 6 (Call of Cthulhu)
"What's in your basement? Something dark and festering? Something that lumbers up the rickety steps into your bedroom while you sleep? We know what's in ours - Call of Cthulhu 5½. And you’ll find it inside. What is it? We took Chaosium's CoC5 and munged it up— with new skills, new occupations, and new ways to handle magic and sanity in the game. And to get your CoC5½ campaign rolling, we present the Randolph Peirce Foundation, a gallant bunch of intrepid investigators based in Arkham, who are looking for a few good members. With floor plans of their mansion, background and history of the Foundation, and a roster of allies you’ll be up and spooging in no time. Which is a good thing, because this issue's scenario "Blood on the Tracks" takes no prisoners. It's The Unspeakable Oath, and it's definitely binding."

I love the Blair Reynolds cover art. Reynolds also did quite a bit of work for Digest Group Publications (DGP).

"This issue's cover is by artist Dennis Detwiller, depicting the arrival of the King in Yellow at the Court of Yhtill. Articles include the Mythos in colonial New England; Lovecraftian films and how to run better games by watching them; and a look at the island of Ponape. Two scenarios dealing with cults are included: in "Cold War" you play Ithaqua cultists in 1990s Toronto; "Two Minutes On High" puts the investigators between warring cults in 1920s New England."

Grace Under Pressure (The Resurrected, Vol 1)
"You are on the sea floor, 1500 feet below the surface. Around you there is only cold and dark — the sun's caressing rays bring nothing to this world. The pressure here is over six hundred pounds per square inch. This is a lethal place. There must be caution in every move you make, or the sea will claim your body and your soul. You and your companions are aboard the RSV Wallaby, a prototype research vessel of your own design. This is its maiden voyage; the attention of the world is upon you.
You are not alone.
And in the hours to come you will die. Unless you can master the fine art of Grace Under Pressure...
Unlike most Call of Cthulhu adventures, "Grace Under Pressure" is not intended for campaign play. This book includes eight pre-generated characters for use with the game, as well as guidelines for your players to make up their own. Extensive notes on how to present the adventure theatrically are included, with emphasis on lighting, props, and sound effects. The adventure uses a unique dual-Keeper presentation, but can also be run by a single Keeper."
