Poor photo; gray on some of the pieces is weird light reflection. If I had time, I would rephoto puzzle under different lighting conditions. No repairs needed. Cut by Waltham Puzzle Co. in Waltham, MA, semi-interlocking, large round knob. Picture is a photo (I think). Google search shows Pendletonn Path in the Oregon trail system but cathedral in background suggests England. If artwork, scene could be "composed".
