While the Conan character known as "Snow Raven" is categorically listed as appearing in three issues of the Savage Sword of Conan magazine, in actuality she only appears in two of them:

• The Savage Sword of Conan #95 - Night of the Rat!
• The Savage Sword of Conan #107 - The Eyes of G'Bharr R'Jinn!

Her third "appearance" would be on the cover but but not in the story itself.

• The Savage Sword of Conan #132 - Master of the Broadsword

There is a woman in this issue calling herself "Snow Raven", but she is clearly not the same character. She is much younger, claims to be the surviving princess of a now destroyed clan and her hair is also "Raven" colored, not white, adding to the distinction.

Presumably the SSoC #132 cover artist Joe Jusko was told a character named Snow Raven was in this issue and he crafted the one that exists on the cover of Savage Sword of Conan #132.
