Allison Hoffman contrasts two versions of the Passover prayerbook – one for American GIs during WWII and another classic, the Maxwell House Haggadah:
A onetime advertising manager for the Yiddish Forward, [Mad Man Joseph] Jacobs set up an agency in 1919 that specialized in marketing to the large and rapidly assimilating Jewish population.
