(57) An advertising medium for mounting on scaffolding structures, applicable to said
structures, for fixing thereon by means of tensors secured in holes or eyelets made
for these purposes close to the edges of a piece of canvas which is the basis for
the medium as a whole; said canvas also has a transparent strip secured on one or
both sides and in its centre so that, between it and the transparent strip, an area
or pocket is formed for the introduction and placement of another strip carrying the
advertising message or messages. The said transparent strip is secured along one of
its edges, preferably the upper edge, to the canvas, by a weld, while the remaining
three edges may have holes or eyes aligned with similar openings in both the canvas
and in the strip bearing the advertising, through which the appropriate pins or tensors
are used for closing. Likewise, said pins may be placed in alignment with the welded
edge.
