I'll go first!
First I adjusted the levels to get rid of the slightly washed out feel (pun unintended, I assure you). Then I adjusted the colour balance, dragging the slider all the way over to the red. Then I applied the dark strokes filter, then dragged on a black and white layer that formed the border - where the picture shows is black, outside the picture is white, and shades of grey are the partially transparent parts of the image. This layer was set to Lighten so the picture would show through the black areas. Then I added a canvasy texture to give it the painting feel.
