Advance and teaser posters are advertising materials that are distributed to theatres and film distributors well in advance of the film's projected release. BUT, when discussing advances with older collectors, you need to remember that there is a difference between an Advance and a Teaser.

Even though both are used to promote the film before the release, a 'Teaser' poster normally has no credit information at all, so teasers are advances BUT not all advances are teasers. This is not true in all cases, there are occasions where a studio has issued an advance poster and has the word 'Teaser' in the bottom border. (for some reason, studios just won't seem to keep collectors rules:) )

Generally speaking, advances are normally released in most countries in their most common sizes such as a one-sheet or two-sheet, although other sizes were be used in a few promotions.

Depending on the film’s promotional plan, the advance sheet may be identical or may differ significantly from the regular issue one-sheet (the one issued with the release of the film).
