Joe Kubert HAWKMAN page 1962

Page 5 from a Hawkman reprint in Detective Comics #438,
cover Dec 1973 - Jan 1974.
(This was from the DC Comics 100-page Super Spectacular issues)

One difference I see between Kubert's work from the 50s and 60s versus the more recent decades is the further develpment of his personal style such that while he is more casual about details (see the TOR page) at the same time he has a more finished embellishment of his main figures.
