104 Sundays, story and art entirely by Harold Foster, and eight pages of extras.
From the publisher:
As Hal Foster's Prince Valiant enters the 1950's, Val investigates reports of black magic, battles the Picts and even finds time to visit his young son, Arn. Shot from original printer's proofs, Volume 7 will also feature the usual wealth of supplements, including another brace of rarely-seen Foster art, and an introduction by the recently-anointed artist of the ongoing Prince Valiant strip, Thomas Yeates.
This came from the library of Burny Mattinson (1935-2023), an animator, director, producer, and story artist for Walt Disney Animation Studios, from 1953 until his death in 2023. Mattinson directed Mickey's Christmas Carol and The Great Mouse Detective. He was named a Disney Legend in 2008 and was the longest serving employee of The Walt Disney Company, with a career that spanned almost 70 years. His extensive library included numerous subjects and especially large collections of books on Disney, animation, and classic comic strips.
