I found another Star Wars Episode IV Publicity still from it's quality either a magazine scan or a picture printed on poor quality paper: initially I cleaned & enhanced the image & re-sized it. Once re-sized I created a new background layer erased the old background before merging the 2 layers; Once merged I applied several effects to finish.
UPDATE: I decided to boost the contrast a little & to sharpen the image a tad.
