Final Dell issue. The unusual issue numbering would appear to have been the result of the transition of this line of comics from Dell to Gold Key. Some similar issue numberings occurred for certain issues published at the very end of Dell's association with Western Publishing. Bullwinkle (Dell, 1962 Series) #01-090-209 is another such example. No ads in this issue. All 36 pages are comics or comics-related text material.
