It sounds to me to be a reprint since they are in PD. Here's the sales pitch on it they posted:
TREASURE CHEST - GRAPHIC NOVEL
Written and art by various, cover by Adam Ellis.
Bluewater brings back the classic comic book series that started in 1946. Its inspirational stories of sports and folk heroes, saints, school kids, history, science and similar topics were drawn by artists that included such prominent figures as EC's Reed Crandall, Graham Ingels and Joe Orlando, Marvel Comics' Joe Sinnott, and DC Comics' Murphy Anderson and Jim Mooney. Other features included literary adaptations and such typical comics fare as funny animal humor strips.
