Jules Cheret is considered to be the father of the modern movie poster and is credited with bringing movie posters into existence.
Most new movie posters are distributed through a great channel, the Internet. The Internet has had a profound effect in the world of new movie posters. Most cities do not have many retail outlets for new movie posters, but you can easily find them online.
With the passage of time, the cost of new movie posters will rise. However, this value is retained only with the proper preservation. Remember that movie posters were never made to last forever. Never store a movie poster in the attic as light, heat, humidity and rough handling hastens its deterioration. All new movie posters should lay flat in a cool, dry place. This is because if any rubber bands are placed on rolled posters, the rubber may deteriorate over time and stick to the poster. The rubber bands tend to indent the poster, as a result of the applied pressure. If possible, store the posters between low-acid foam boards, as storing in regular cardboard having high acid content hastens its deterioration.
If you do intend to frame the poster, it is better to have it matted, so that there will be no direct contact with the glass of the frame. It is also important to make sure that the backing board is acid free. To protect the new movie poster from dangerous prolonged exposure to UV rays, it is better to use UV resistant glass for the frame.
