Abstract: An automobile window screen is removably disposed between opposing elements of an automobile window frame. The screen includes a pair of flexible and resilient elongated blocks, each of the blocks having a pair of longitudinal edges and a plurality of ventilation holes formed therethrough. The blocks are in abutment at positions along, but slightly spaced from, their longitudinal edges. A flexible elongated screen is abutably disposed between the blocks. The window screen possesses sufficient rigidity to extend to the opposing window frame elements when disposed in the window opening, yet possesses sufficient flexibility to be longitudinally rolled when not disposed in the window opening. Preferably, the blocks are formed from foam rubber, and Velcro strips are used to secure the screen in a rolled condition.
