Abstract
An improved sign frame is provided which will allow for a sign to be quickly and easily inserted in the frame and to be easily removed from the frame. The sign frame has a first side, a second side, a third side and a fourth side. The second, third, and forth sides being formed from substantially identical elongate members which are connected together to form three sides of the frame, the elongate members are generally tubular and have a sign receiving channel to accept at least one sign and secure a stiffening member. The first side defines a sign receiving opening through which a sign is removably inserted The first side is made of a front member and a back member which are identical. The first side front and back members and the second, third and fourth side members are sized such that the two first side members are spaced apart from each other to define the sign receiving opening of the sign frame.
