"Bus Stop Bible Studies are passages of Scripture, often accompanied with a challenging question or thoughtful comment, posted on advertising display panels inside buses, streetcars and subway cars, or on the backs of buses. A typical "study" measures 35" wide by 11" high. 70" wide panels are also available for posting longer passages of Scripture. The studies are designed to challenge and encourage believers and to show something of the character of God to those who may be seeking. Space is available on the display panel to identify the sponsor (church, organization, individual, etc.)." http://busstopbiblestudies.com/
