Claims1
A modifiable sign system comprising a base comprising a substrate comprised of a first side and a second side and a steel sheet attached to said first side of said base, a first sheet comprised of plastic material which is removably disposed over said first side of said substrate, a second sheet comprised of flexible magnetic material which is magnetically attached to said steel sheet through said first plastic sheet, a third sheet comprised of flexible magnetic material which is magnetically attached to said substrate through said first sheet, a retaining clip attached to a top edge of said base and a J-shaped channel attached to a bottom edge of said base for removably retaining top and bottom edges of said first sheet respectively, and a frame for holding said base, said steel sheet, and said retaining clip, wherein:
- (a) said first sheet has a thickness of from about 10 to about 20 mils,
- (b) each of said sheets has a thickness of at least 25 mils, provided that said thickness of said first sheet is less than about 70 percent of the thickness of said second sheet and said third sheet,
- (c) said base comprises a hardboard material.
