ADVERTISING MEDIUM

The invention relates to an advertising medium (1) with a canvas (2) and a tensioning frame (3) that stretches open the canvas (2) from a transport position into a display position and has a first part (4) with a mounting (5) and a first set (6) of flexurally elastic tensioning rods (7), which are rigidly anchored on the mounting (5) and protrude parallel to one another away from the mounting (5) in the transport position, and a second part (8) with a sliding sleeve (9) and a second set (10) of flexurally elastic tensioning rods (11), which are rigidly anchored on the sliding sleeve (9) and protrude away from the sliding sleeve (9) in a direction opposite the first set (6), wherein the sliding sleeve (9) can be moved on the first part (4) between the transport position, in which the sliding sleeve is pushed over the first set (6), and the display position, in which each of the tensioning rods (7, 11) of the two sets (6, 10) is bent and stretches open the canvas (2).
