I think the only time there's an illustration of a helmless Grey Maiden is in Pathfinder #12, Crown of Fangs. That's a very specific Grey Maiden, though.
All of the PC base class illustrations as well as the Eldritch Knight illustration are "iconic" PCs from the Pathfinder Adventure Paths. If you buy one book from each of the first three APs (Pathfinder #1 through #18, each AP is 6 books long), you'll have stats for each of the twelve. Rise of the Runelords has Valeros the Fighter, Seoni the Sorceress, Kyra the Cleric, and Marisel the Rogue. Curse of the Crimson Throne has Seelah the Paladin, Lem the Bard, Harsk the Ranger, and Ezren the Wizard. Second Darkness has Sajan the Monk, Lini the Druid, Amiri the Barbarian, and Seltyiel the Eldritch Knight. Note that those stats will be 3.5 versions of the characters, so they'll need conversion to Pathfinder rules.
