This article and checklist present the contents of the Spencer Album of Marcantonio Raimondi prints, long considered to be lost. By examining its composition and tracing its provenance from the Spencer collection at Althorp House to the John Rylands Library, Manchester, we offer new insight into how attitudes toward Marcantonio Raimondi’s work evolved during the eighteenth and nineteenth centuries, particularly in Great Britain. Our article also explores Victorian collecting practices and the importance of the graphic arts for Mrs Rylands vision for the Library to be dedicated to her late husband’s memory.
