This condition guide does not follow any standard published guides. Frankly, I don't believe in a grading system and don't like them. It is my opinion that poster for sale should be described as well as possible, versus lumping them into a specific grade. There are so many elements to judge and that can leave the door open for interpretation. It is my recommendation, as your host, to focus primarily on the written descriptions in each listing and determine whether the condition is acceptable to you and your collection.

Upon first glance at this poster you may think it to be a "Fine" grade but upon closer inspection it may have very minor defects such as pinholes, minor paper loss in the folds or around the border, or non surface breaking bumps and bruises for modern posters etc. It will not have significant fading or image/surface loss. This grade may have a only one defect but "Fine" on all other accounts.
Most posters will fall into this grading category.

Everything else... These items are probably in need of restoration or generally unattractive but still have value.
