Led Stainless Steel Sandwich Boards, Shape: Square

The increased competition for poster space and the inconveniences of an advertising tax led the advertisers to generate a type of advertisement that moves ^[1] a handy sales tool to promote sales. ^[2] The term "sandwich man" was coined by�Charles Dickens. ^[3] He described these advertisers as "a piece of human flesh between two slices of paste board". ^[1] Sandwich boards were most popular in the 19th century, and have largely been supplanted by�billboards, which are more effective in advertising to passers-by who are now likely to be in�automobiles, rather than traveling by foot. ^{[4] [ citation needed ]}

However, they are still frequently to be seen on major shopping streets such as�Oxford Street,�London;�Champs �lys�es,�Paris, and�42nd Street,�New York City, where they are used to advertise offers from particular stores most often in adjacent side-streets. ^{[ citation needed ]}

There are generally two types of sandwich boards.

The carried version is usually attached to straps acting as�suspenders, allowing the person wearing the boards to carry the weight on his or her shoulders and keeping the boards balanced on the wearer. The wearer might also pass out�flyers�or shout advertising�slogans. These sandwich men are seen parading in a queue cladded in a specific costume. ^[5] They were gorgeously dressed at the beginning but later they were portrayed wearing shabby clothes in many illustrations that failed to attract consumers attention. ^[1] In many cities of the world these type of advertisements are considered illegal and is a punishable offence. ^[6] According to the�London Hackney Carriage Act 1853�and Section 9 of the�Metropolitan Streets Act 1867, it is not lawful for any person to carry any picture, placard, notice, or advertisement, on any carriage or on horseback or on foot except those which are approved of by the Commissioner of Police. ^{[7] [8]}

Another is called "A-board" which is kept next to the stores, on public transport grounds, such as sidewalks or pedestrian zones to draw the attention of the customers passing by. ^[9] These A-boards resemble the shape of letter A. In some modern A-boards the conventional two boards have been replaced by a single board hanging within the frame. A-boards are most typically deployed in busy pedestrian areas to advertise businesses. Advertising the business website or social media page on these boards helps the business get recognized locally as well as internationally. ^[10] This kind of advertising is most popular among bars and restaurants. ^[11] For some small businesses is it the main type of advertising. ^[12]

Many different types materials are used to make these boards. The carried type is generally made up of light materials like�cardboard�or paperboard ^[13] and yarn to hang it to the shoulders. ^{[ citation needed ]}

The conventional types of A-boards are traditionally made with any rigid flat material such as fibre board, chip board, wood,�plyboard�or�MDF. Modern A-boards are made with plastic, steel or aluminum and in some of them the hinges are made with leather. Cheaper A-boards are made with wood-frame with cloth nailed upon and printed with screen-print or painted by hand.�Chalkboards�are also used as a A-board material, with the advertisement messages written by hand.
