Subject: [ARSCLIST] Billboard and Cashbox street dates
Does anyone know or remember when new issues of Billboard and Cashbox hit the newsstands, ca 1956-1957? I believe Cashbox was subscription only, so I may be asking for the mailing date here. I believe that Billboard was actually available at some newsstands before subscribers received their copies. Cashbox covers gave a Saturday date, while Billboard's was a Monday date.
