Just about every area of antiques and collectibles can be divided into several different sub categories. It could be collecting the denomination or country of origin of coins, a certain glass company or pattern, or even a certain type of manufacturing process like majolica pottery.
This is true for enamel advertising signs, and one of the ways you can do this is the style of manufacturing of the sign itself and how it can be displayed.
The first type is a flat one-sided sign. This style has advertising on just one side of the sign, and this would be perfect to attach to a wall or the front of a building. With only one side having the advertising, the back will have just one color of enameling.
The second type is called a flat two-sided sign. This style has advertising on both sides of the sign, and most of the time this type of sign will be in a stand or frame of some type to help see both sides.
The third type of sign is a flanged two-sided sign. This type of sign has a built-in 90-degree angled mount on it that allows the sign to come out from a wall or even a side of a building.
The next type of sign is called a curved sign. This sign will have a curve in it to go around items like a telephone pole, a street light or even the corner of a building.
Another type are gasoline pump signs, and they will advertise the brand of gas that it is. Not only are there gasoline pump sign examples for automobile gas, there are also some examples known for marine and aviation gas known as well.
The last example is called a neon porcelain sign, and this type has neon lights on it. This type of sign can light up and you can see the sign better at night, and the most notable type is on a movie theater. You could also find this hanging in a window of a business.
