Abstract: A weather-proof and inexpensive advertising pocket for attachment to a shopping cart in a manner permitting direct viewing by a user of the cart of printed matter insertable into the pocket. A continuous back is of generally rectangular configuration. A transparent window of approximately the same horizontal width as the back, but of less vertical height, is aligned in parallel planar relationship with the back such that the window spans most of the area of the back except along one horizontal edge of the back. A lip is of approximately the same horizontal width as the back and is of sufficient vertical height to span the area of the back not spanned by the window and to overlap a small portion of the window in a manner preventing precipitation from entering the pocket. An internal pocket area is provided by sealing the back, window and lip about the edges of the back.
