Wikipedia: "Prefacing the Schmitz tale "The Second Night of Summer",[in which humans on the planet Noorhut face an attack from aliens and are, unbeknownst to themselves, saved by the actions of a single woman with psi powers, Granny Wannattel, with the sole help of a friendly alien she calls her pony."
Granny, eh. Well, the cover would have to take some liberties.
That's what the entry says for "LEGACY," which may actually refer to his, you know, Legacy. This particular book is also referenced as a retitle of "The Tale of Two Clocks."
The stylized signature tells you this is awork by Bob Adragna, who was something of a man of mystery until this interview. A large collection of his work can be found here, on Flickr. It's his site.
