Picture discs are gramophone (phonograph) records that show images on their playing surface, rather than being of plain black or colored vinyl. Collectors traditionally reserve the term picture disc for records with graphics that extend at least partly into the actual playable grooved area, distinguishing them from picture label discs, which have a specially illustrated and sometimes very large label, and picture back discs, which are illustrated on one unplayable side only. The beginnings A few seven-inch black shellac records issued by the Canadian Berliner Gramophone Company around 1900 had the "His Master's Voice" dog-and-gramophone trademark lightly etched into the surface of the playing area as an anti-piracy measure, technically qualifying them as picture discs by some definitions. Apart from those debatable claimants for the title of "first", the earliest picture records were not discs, strictly speaking, but rectangular picture postcards with small, round, transparent celluloid records glued onto the illustrated side. Such cards were in use by about 1909. Later, the recordings were pressed into a transparent coating that covered the entire picture side of the card. This novelty product idea proved to have a very long life. In the 1950s and throughout the rest of the vinyl era, picture postcard records, usually oversized and often featuring a garish color photograph of a tourist attraction or typical local scenery, were issued in several countries. These and similar small novelty picture records on laminated paper or thin cardboard, such as were occasionally bound into magazines or featured on the backs of boxes of breakfast cereal, are usually not classed with the larger and sturdier discs that were sold in record stores or used as promotional gifts by record companies, but a few featured famous performers and are now eagerly sought by collectors of those artists' records. The first picture discs of substantial size, sold as records meant only to be looked at and played, not put into a mailbox, appeared in the 1920s. Their first wave of significant popularity did not arrive until the start of the 1930s, when several companies in several countries began issuing them. Some were illustrated with photographs or artwork simply designed to be appropriate to the musical contents, but some graphics also promoted films in which the recorded songs had been introduced, and a few were blatant advertising that had little or no connection with the recording. Some politicians and demagogues explored the potential of
