A reminder card having a printed message is printed directly on the mailing envelope on the rear lower portion of the envelope and is perforated for easy removal. The reminder card is slipped into a window pocket on the front face of the envelope to display the reminder message. A base for forming the envelope into an upstanding display is formed by bending a flap on the bottom rear of the envelope upward into an arc and adhering the flap to a gummed flange formed from the outer edge of the sealing flap of the envelope to create a triangular shaped display capable of remaining upright. A magnetic strip glued to the envelope allows the envelope to be secured to a vertical ferrous surface.
