Abstract: A mailbox cover comprising a flexible sheet having a composite of a plurality of layers. The layers having a first layer decorated with graphics and an underlying second layer magnetically polarized in a first direction so that the second layer is magnetically attracted to a metal mailbox. The plurality of layers further comprising an underlying third layer magnetically polarized in an opposing second direction to the second magnetically polarized layer so that the third layer is magnetically attracted to a metal mailbox. An underlying fourth layer is decorated with graphics. The sheet further comprising a perforated cuts parallel to preselected edges of the sheet so that the perforated cuts allow strips of the sheet to be removed to reduce the length and width of the sheet to adapt to different sizes of mailboxes.
