Condition Guide

We assess the condition of each item using three categories: Good, Fair, and Poor. We strive to ensure that any significant flaws are clearly shown in the images provided and detailed in the accompanying condition statement.

Good

The item presents well, with no significant flaws, and is in frameable condition. Minor imperfections—such as light spotting or offsetting, small blemishes, tight margins, neatly repaired tears, or discreet/professionally executed restoration—do not materially detract from its overall appearance.

Fair

The item shows noticeable flaws but remains in frameable condition. Some buyers may feel these imperfections affect its visual appeal. Typical issues may include more prominent spotting, blemishes, bleed-through from the reverse, obvious offsetting, visible or extensive restoration, wear along fold lines or junctures, small wormholes, trimmed or closely cropped edges, or less carefully executed repairs.

Poor

The item has major flaws that significantly impact its presentation and/or suitability for framing. These may include heavy spotting, staining, bleed-through, offsetting, unrepaired damage, or poorly executed repairs such as tears, holes, or areas of paper loss (including within the printed image). The item may also be fragile and prone to further deterioration.
