126 Pinhole Test Sunset

This is an image I took for a photography class when I was attending college. All I can remember about it is that I used a 126 Kodak 100 ASA film cartridge and that the pinhole didn't turn out to be real round. I was thinking that I converted a Kodak Instamatic X-15 into a pinhole camera, but could never find the actual camera. I either got rid of it for some unknown reason or converted one of the three I have back to normal.
