DIY: A "Continental 2001" picture frame part2

Yes once more a picture frame out of the old Continental 2001 gas range! See here part 1!
Now I've used the front glass of the gas range, which is smaller as the other glass part, but certainly heavy, too.

I've put a photo-collage out of self-portraits, which I made in 2006 with my Voigtländer Vitomatic II and Agfa Silette (Agfa Apotar 1:3.5/45mm and Pronto shutter), into the frame.
