Here Comes The Circus is a 16 MM film by Castle Films. This is vintage film still in its original box which is still very nice with great clown graphics. From my research, it is possible this is from the 1940's or a bit later.
Box size is 4 x 4 x 1 inch. I have checked and it is the right film in the box. I did notice that the very end looks like it has a small piece broke off but will not affect the actual graphics that are further on into the strip.
