Suppose you had a specimen book for a single face. Say that single face is Eine Schraffierte Antiqua or Reform Grotesk. Let’s further say the book shows a series of sample settings, some of which include dates. The book itself is undated. There are only dates in the sample settings. Is there anything one can infer from the dates? Like, in this Eine Schraffierte Antiqua specimen I see 1914, 1918 & 1911. The Reform has a sample setting with a single date of 1924. Does any of this mean anything?
