Despite his immense popularity in the '40s, Rudolph didn't appear in a comic until 1950...
...when he finally received the first in a series of annual comic books from DC Comics!
To be continued...
Written by Sy Reit and illustrated by Rube Grossman, this 1950 annual was the first of a series that ran until 1963.
The concept was revived in the tabloid-sized "Treasury" (10" x 14") format in 1972 and was published annually (except in '75 and '77) until 1978.
(Both DC and Marvel experimented in the 1970s with the over-sized format.
They were much bigger than normal comics with cardstock covers, though the interior pages were printed on the usual comic book paper stock.)
The series was a more-or-less sequel to the original story (which we presented HERE.) and song.
(The animated TV special that tells a totally-different version of the tale didn't appear until 1964.)
One thing you'll note is the unique idea of including activity pages as part of the story, giving us perfect chapter enders and openers in our serial presentation format.
