An enamel sign chips as soon as something strikes it, and it rusts from the nail outward when the garage is damp. In the overview Security for collectors it is a flat piece that people screw to the wall and then forget.

What gets ruined without a thief

Damp, rust, a stack with no interlayer, sun that bleaches the color, a nail through the original hole into a wet wall. You store dry, with air, nothing hard on the enamel. For hanging, a wall that does not sweat, and a fixing that does not put more holes in the sign.

When someone comes

On the outside wall facing the street it is an invitation. Rare signs hang inside, inconspicuously, or lie dry in the locked room. They are easily small enough for a car trunk. The list states motif, dimensions, damage in the enamel.

The folder

Motif, dimensions, maker if known, receipt, photo in daylight so the chips show.
