104 Sundays, story and art entirely by Harold Foster, and eight pages of extras.
From the publisher:
In volume 17, Valiant is back in Britain, where he finds himself in the middle of a conflict between Saxon settlers and violent Viking raiders. Gawain's return journey to Camelot is fraught with romantic misadventure and Young Galan goes on a hunt to capture the fabled unicorn. Meanwhile, Arn is enslaved and held for ransom.
This volume also includes a supplementary section of rarities and extras, curated by Foster historian Brian M. Kane.
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.
