* "Jeff the Seal" - sea lion
* Niagara Falls plunge folklore 

The front page has a one column heading: "Seal Does a Flip Over Niagara" with photo showing Tommy Haines, the boy who spotted "Jeff the Seal" down river. (see images)
Complete with 40+ pages, small binding holes along the spine, small address stamp in the masthead, generally nice.

Background: In late May 1963, the dramatic escape and recapture of "Jeff the Seal"—actually a California sea lion—became a defining piece of Niagara Falls folklore that fundamentally shaped the trajectory of regional wildlife tourism. After slipping out of the newly opened Marine Wonderland & Animal Park (which would later evolve into the famous and controversial Marineland Canada), Jeff headed into the upper Niagara River and was later discovered alive miles downstream at Niagara-on-the-Lake, leading to a frantic, biting recapture by park owner John Holer. The historical significance of this event lies in how it was brilliantly exploited as a foundational marketing myth; by boldly claiming Jeff was the first marine mammal to survive a miraculous plunge over the deadly Horseshoe Falls, Holer weaponized the public's fascination with Niagara daredevils to skyrocket the small park's attendance and local fame. This single incident not only established the park's early financial viability but also catalyzed the rapid expansion of large-scale, captive marine mammal entertainment in Canada, setting off a multi-decade legacy of massive commercial success that eventually gave way to intense modern scrutiny and shifting public ethics regarding animal captivity.
