Mark VII Limited

Mark VII Limited was known for its production logo attached to the end of its productions. The logo, in use in one form or another for much of the company's existence, showed the hands of Jack Webb's construction foreman Harold C. Nyby holding a stamp against a sheet of metal. As a timpani roll played, he struck two blows on the stamp with a hammer and then removed both tools to reveal the Roman numeral VII indented into the sheet.

The origin of the name "Mark VII" is unclear. One source said the name meant nothing, and that it was made up over coffee one day. Another source says Webb just liked the look of the Roman numerals.

The Mark VII production logo is one of the more recognizable logos of its time and has become iconic, with many instances of filmmakers and production companies paying homage to it in various ways, most notably Williams Street Productions, originally Ghost Planet Industries, of Adult Swim/Cartoon Network programming, whose logo utilizes the same drumroll/hammer clinks soundtrack from the 1967 Mark VII logo. The Mark VII Limited logo was also spoofed at the end of the 1954 Woody Woodpecker cartoon Under The Counter Spy. In this spoof, the man accidentally hits his thumb with the hammer and yells "OUCH!", then pulls the hammer away to reveal the ending title card. The man's voice was supplied by Daws Butler. A 1955 The Three Stooges short Blunder Boys not only was a parody of Dragnet, but ended with Larry being stamped with "VII 1/2 The End" on his forehead. Gunther-Wahl Productions used a similar card at the end of its cartoons.

The logo was remade multiple times during the company's history. It is reported that the early logos featured Jack Webb's hands but the later logos featured Ivan Martin's. Martin was the director of studio operations for 20th Century Fox at the time of his retirement but worked in the studio's visual effects department during production of the logos.
