Rudolph on Ebay
Rudolph the Red-Nosed Reindeer comic book National Periodical Publications (aka DC Comics) published their title Rudolph the Red-Nosed Reindeer between 1950 and 1962-1963. There were 13 regular issues in this series.

DC's Rudolph title was an unnumbered series, with one giant-sized issue being released every year before Christmastime. The interiors featured whimsical stories and artwork designed to appeal primarily to smaller chidlren. In addition, each issue featured various Christmas-themed puzzles and games.

The last issue, released in 1962-1963, featured a cover similar to the 80 Page Giant/Annual comics which were then becoming a popular part of DC's publishing schedule.

Note: In the 1970's, there were several Rudolph issues of the Treasury-sized Limited Collectors' Editions (see fourth image below), those oversized comics that were published by DC in the mid-70's to the early 80's. The contents of these were probably reprints of items from this series.
