The first series, “Timely’s Greatest: The Golden Age: Sub-Mariner - The Pre-War Years,” seems to be named okay, but the second series, “'Timelys Sub-mariner Everett Post-war Omnibus HC”, focusing on the Post-War Years, has an awkward title without punctuation and does not follow the pattern of the first series.
I suspect the title “Timelys Sub-mariner Everett Post-war Omnibus HC” should be renamed “Timely’s Greatest: The Golden Age: Sub-Mariner - The Post-War Years” to be consistent.
Or they should be lumped together as Vol. 1 and Vol. 2 of “Timely’s Greatest: The Golden Age: Sub-Mariner” with coresponding Titles of The Pre-War Years and The Post-War Years.
