Robert Walter Cain Ltd The file contains a letter from the brewers, who released products under the name Peter Walker & Son [amalgamation name of Robert Walter Cain Ltd and Peter Walker], regarding old label designs [examples included] and Bawden designing a new one. The file also contains, Bawden's artwork [faint unrelated sketch on verso] and printed versions of his label designs, including text and the firms' unicorn logo. The logo has been stamped to different colour backgrounds and using different colour inks, it appears these were used to cut and stick onto designs [spaces missing]. 1951
