It is very important, in the case of sandwich boards, to incorporate shape, colour into the surrounding architecture so that they form a harmonious whole. On the other hand, they must be visible, otherwise they could be a threat to a passer-by :).

    The advantages of sandwich boards include: a possibility of use in many places without a necessity to mount the rack (as opposed to the banner) and the ability to hand-advertising exchange of advertising contributions (depending on the design).

Sandwich boards are made of metalwork, metal or wood construction, or mixed construction.
