William K. L. Dickson: Dickson Greeting (1891)

Nel 1893, la costruzione del primo teatro di posa al mondo era terminata ed Edison con il suo assistente William Dickson poté iniziare a produrre pellicole per kinetoscopi. I primi filmati di Edison mostravano brevi esibizioni di ballerine, acrobati, sportivi, girate perlopiù all’interno del Black Maria, piccole curiosità per gli utenti dei kinetoscopi.
