The strip itself has continued to the present day and has since its start belonged to the comic syndicate King Features.
A single volume includes two years of Sunday strip pages as well as some supplementary content, such as interviews and introductions.
The largest reproduction of Prince Valiant, yet, is in the Artist's Edition book: Fantagraphics Studio Edition: Hal Foster's Prince Valiant, ISBN 978-1-60699-897-7, also published by Fantagraphics Books, measuring 17 by 23.25 inches (432 mm × 591 mm).
[6] Hal Foster originally drew a whole Prince Valiant Sunday page on paper stock measuring 26 by 35 inches (660 mm × 890 mm), which makes this collection series' area size equal to about 16 percent of the original art size.
This strip was a tale he drew when he split up the page he was allowed for the Prince Valiant strip during the Second World War, due to a paper shortage and newspaper space being at a premium, splitting his full one-page spread between three-quarters of a page for Prince Valiant and one-quarter for The Medieval Castle, in order to make it easy for editors to remove the non-Prince Valiant strip to free-up space for something of greater importance in wartime.
