Abstract: A promotional display comprising a chamber having front and rear panels with inside and outside surfaces, for containing between expanses of the inside surfaces of the panels a first liquid. At least a portion of the outside surface of the front panel comprises a view surface which allows viewing of liquid flow inside the chamber. A liquid reservoir is positioned adjacent the chamber for containing a second liquid therein, which second liquid contrasts with and is not miscible with the first liquid. A restricted liquid flow path is located between the chamber and the reservoir, which allows flow of the second liquid into the chamber and across at least a portion of the view surface of the chamber.

Abstract: A pocket-sized battery-operated flashlight adapted for use as an advertising premium which is typically used in close range to illuminate a keyhole of a lock to open the lock with a key, for which close range use only a portion of straight-away light is needed, so that available excess light is diverted radially to illuminate a display to thereby contribute to the value of the flashlight as a premium.

Abstract: A hand held calculator with keyboard buttons to display numbers on a screen as a display foreground, and a rearwardly disposed panel with an imprinted commercial message expressed in words/letters as a display background, in which although the foreground is over the background, a viewer is not confused because the numbers and letters are readily distinguishable from each other.

Abstract: An article of manufacture having voice-recording and recorded voice-playback mechanisms having a cube external shape, which is disguised as a household decorative fixture, e.g. a photograph holder, and internally bounding an echo chamber, e.g. a volume of at least 60 cubic inches, such that there is sufficient clarity in the played back recording due to the use of the echo chamber to enable recognition of the voice, to thereby add to the gift value of the article of manufacture.
