the copy I picked up today for $2.49 looks just like this.

First Edition, 1929
Planet of Peril
Derring-do on a world of primitive monsters!
When Robert Grandon swapped bodies with a prince of the planet Venus, he was concerned only with the thrill and interest of living on a different world. But the situation he found himself in was hardly that of a leisurely sightseer. Instead, he found himself smack in the center of a whirlwind of intrigue, danger, and desperation.
Planet of Peril is a science-fiction adventure on a world of semi-barbaric nations, ferocious beasts, gigantic reptiles, and maidens in distress!
I also found the second book of the Crusader stories, I've had book one for the longest time. but have been waiting to get this one before I started the series. Woo Hoo!
And finally, I snagged & VHS tapes of MST3K for a buck a piece.
