Starting in 1967 and continuing til 1969 Irwin Allen, in an attempt
to boost the ratings of his shows on ABC (Voyage to the Bottom of
the Sea and Land of the Giants) sent flyers each week with artistic
(if somewhat inaccurate) drawings from that week's episode to
newspapers and magazines all over the country. Unknown to most people
however, he tried the same tactic with the third (and regrettably,
last) season of his CBS adventure LOST IN SPACE.
