As I Opened Fire (Set of 3 66x 53cm Rare Posters) art picture by Roy Lichtenstein. 66cm x 53cm (26" x 21") art print / poster. Thousands more prints also available, with free delivery worldwide. As I Opened Fire was originally painted by Roy Lichtenstein in 1964 & is owned by the Stedelyk Museum in Amsterdam. Although this print is an open edition (not limited to a set number), it has not been published in as great a quantility as some of his other works, it has therefore become a more collectable piece. As I Opened Fire is always sold as a triptych (i.e. three separate prints sold as one). It is a superb example of Lichtenstein's comic strip style which made him one of the leading figures of the 1960's Pop Art Movement.
