ABSTRACT:
A photo filmstrip has plural perforations arranged along each of lateral edges and at a regular interval. A trailer is retained to a spool to be wound about the spool in a roll form. A retainer portion is formed at a smaller width by cutting each of the lateral edges along a first line being substantially perpendicular to the lateral edges, and by cutting the trailer along second and third lines being substantially parallel to the lateral edges. The retainer portion is adapted to be retained on the spool. The first line lies on one side of one of the perforations having been arranged before forming the retainer portion along the lateral edges.
