What is Advertisement?

Legal Definition
A 'notice' published either in handbills or in a newspaper.

2. The law in many instances requires parties to advertise in order to give notice of acts which are to be done; in these cases, the advertisement is in general equivalent to notice.

3. When an advertisement contains the terms of sale, or description of the property to be sold, it will bind the seller; and if there be a material misrepresentation, it may avoid the contract, or at least entitle the purchaser to a compensation and reduction from the agreed, price. Kapp's R. 344; 1 Chit. Pr. 295.
