The support comprises at least one sheet of a substantially rigid and foldable material having the presentation face ( 111 ), an elastic member ( 110 ) for bending the presentation face ( 111 ) of the sheet and strips ( 39 ) for keeping the presentation face ( 111 ) of the sheet in the bent state, which strips ( 39 ) oppose the elastic member ( 110 ). The strips ( 39 ) opposing the elastic member ( 110 ) for keeping the presentation face ( 111 ) of the sheet bent are designed so that the force is exerted at discrete points distributed along the presentation face ( 111 ) of the sheet by a plurality of strips ( 39 ). |
