We're always happy to see the Queen of Hearts step out.  From Los Ingleses Tales Como Son Carácter, Leyes, Usos y Costumbres del Pueblo Inglés, y Todas Sus Extravagancias by Tomás Bertrán Soler, 1858.

Here's the secret meaning of the Queen of Diamonds*: "Don't desire to be high-prized."  From The Idler, 1895.

*Note the diamond motif at the queen's feet.

We've been keeping one of our latest publications under the radar, lest it fall into the wrong hands.  But we felt safe sharing it with Clint Marsh (of Goblinproofing One's Chicken Coop fame).  From his review in The Pamphleteer:

A master of practical esoterica, Prof. Oddfellow (a.k.a. the inimitable Craig Conley) follows in the footsteps of magicians throughout history in tracing his lineage to a potent fabulous ancestor, in this case Elizabeth of York, the mother of Henry VIII and the woman immortalized as the Queen of Hearts in the familiar deck of playing cards we've all seen.  Instead of climbing the family tree back toward Elizabeth, though, Conley begins with her and comes down through history toward himself.  This approach makes perfect sense to anyone bent on establishing a blood connection to a particular figure from the past, and it seems to involve less risk of falling down the wrong genealogical rabbit hole.  ... [Heirs to the Queen of Hearts: Tracing Magical Genealogy is] a wonderful new addition to his teeming brood of bibliomantic offspring.
