I found these in two books called "Winsor McCay: Early Works III" and "IX" and they are really great. I think other Objectivists will enjoy them. Looking through his work I am very impressed by how he supported the free market, industry, science, freedom and how anti-religion and superstition he was. His work is not above criticism however. He very often cast wealth, money and greed in a negative light while glorifying immoralities such as public education. In any case, his drawings are fantastic and many of the ideas are too. I hope you enjoy them as I do!
This first one is AMAZING.
