A display sign for use with a display system includes a thermoplastic sheet having a first region having a first thickness, a second region having a second thickness less than the first thickness, and at least one fastener. The second region is adjacent to the fastener. A volume of material in the fastener plus a volume of material in the second region is generally equivalent to a volume of material in an area of the first region, the area of the first region being equivalent to the area of the second region. A method of forming a display sheet includes providing a thermoplastic sheet, and drawing at least one fastener from the thermoplastic sheet while in a plastic state. The material drawn from the sheet to form the at least one fastener results in a region of reduced thickness of the sheet adjacent to the respective fastener. |
