It is important to bear in mind that the collection poster is an advertising paper that is 20 or 100 years old. The conservation rules for collecting prints cannot be applied. Most of the prints were made in small formats, on quality paper and were immediately framed or filed in folders or drawers for prints. However, most of the posters were printed in large formats, on poor quality cheap paper, and were posted on the street for 8 weeks. Film distributors sent folded posters to cinemas, bullfighting companies sent folded posters to bullrings, and generally those who kept a poster used to fold it. Given this, in no case can a poster be found without the slightest flaw.

Therefore, the true values ​​of a poster are the design, the lines, the colors, what it represents and the impact it is capable of transmitting.

The following assessment is used to indicate conservation status:

A Poster in very good condition. It may present some negligible tear in the margins, it does not present any lack of paper. The colors are fresh and there are no stains.
A + Perfect state of conservation, very rare to find a specimen in this impeccable state.
A- It may have a slight bend, tear or small lack of paper in the margins. If you present a restoration, it is successful.
B Poster in good condition. It presents tears, some stains and some paper missing, never affecting the crucial area of ​​the design. The colors are fresh and the poster has a very good overall appearance.
B + The poster may be restored. Flaws are slightly visible.
B- The poster is restored, there are some defects and slight loss of color in the fold marks.
C Poster in fair condition. There are tears, stains, crease marks and or missing paper that can partially affect the crucial area of ​​the design, the colors may be somewhat washed out, and the poster has an overall fair to good appearance.
C + The restorations are visible.
C- It requires restoration.
