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.
