ELECTRIC EYE REVEALS AD IN MIRROR (Feb, 1934)

ELECTRIC EYE REVEALS AD IN MIRROR

Designed to be installed in the lobbies of hotels and public buildings, a new advertising device offers a passer-by a chance to inspect his appearance in a mirror, and invites him to take a folder from a pile on a shelf. When he reaches for a folder, he unwittingly interrupts a beam of light that falls upon a photo-electric cell. Brilliant lights automatically flash on behind the mirror, which is now seen to be transparent, and illuminate an advertisement within the cabinet for a predetermined period of time.

    Does this constitute prior art for rollover web ads?

    Those darned pop-ups are older than we realized!
