Here is a very cool-looking illustration by
Robin Davies from the
Ladybird book
"He-Man and the Lost Dragon". Like many of the Ladybird books
Castle Grayskull was seen as a base of operations for the
Heroic Warriors, hence why all fours warriors meet there. I like the way
Stratos is casually leaning against the window ledge, but full points go to Robin Davies for illustrating quite possibly the most relaxed
Teela ever seen! Also note that
He-Man has clearly been based on his model sheet in this illustration...
