Unlike the Halloween edition of other children's magazines I've seen over the years which might offer a few pages of Halloween, a poem and a craft or two, this October 1950 is chock full of treats and goodies. Almost every page features some form of Halloween enjoyment along with some great art.
Much of the art in the book was illustrated by the Art Editor, Fern Bisel Peat. I couldn't find much more than a cursory overview of Fern. She lived from 1893 to 1971 and was an illustrator for Playmate magazine from the 1930's to the 1960's as well as an illustrator for Ohio Art toy company. Other artists that appear in the magazine are Elaine Eads and Angela Price, but even less information about them is available.
Sorry, but some child has ruined the connect the dots surprise for you. It was nice of them to add an eye and complete the brim of the hat though.

"Children's Play Mate" merged with "Jack and Jill" magazine in 2008.
