Auf Yumpu gibt es die Boxoffice magazine Ausgaben von 1948-1965. Thema sind Kinos in Amerika (via jurnsearch.wordpress.com):
«these magazines are a superb resource for theater historians, but to say that they are disorganized would be an understatement. For now, I’m concentrating on the years containing the most drive-in theater news, 1948-1965. If you’ve got a list for other years, please let me know.»
