There are two other Ripley's Believe It or Not! series!
The one in 1949 (ended 1950) was hosted by Robert Ripley himself in the beginning.
The one in 1982 (ended 1986) was hosted by Jack Palance and his daughter Holly Palance and then with Marie Osmond. (This is the one that I remember the most, its opening was spooky.)
This incarnation of the franchise is a poor shade of the 1982 incarnation.
