I made them for the boys in my den four years ago. Sorry I don't have photos, and I am not much with graphics programs. Here's asomething I slapped together using MS Paint:

If you're interested, here's how I made them:
I used rough cedar (sanded on one side). Each 'plaque' (it's actually a shelf) requires a piece of 1" x 12" x 31.5" (for the back); a 1" x 6" x 31.5" (the shelf); and two right triangles 4" x 4" (cut from a 1x6 x 8ft piece). The length of 31.5" is so that you can make three shelves from a 1"x12"x8' and a 1"x6"x8' board. One more 1"x6"x8' gave me enough triangular brackets for all 8 shelves.
After you cut the 1x12 and 1x8 boards to length, trim the corners, cutting 1 3/4 x 1 3/4 triangles off all four on the back and off the from two corners of the shelf. Attach all parts using 2" wood screws from the back. There's no need to fasten the shelf to the brackets. Add cup hooks an inch from the bottom of the brackets to hold the arrow.
Decorate the shelf with shoulder patches from the right and left shoulders outside the brakets; ranks, arrow points, Webelos colors and compass points between the brackets; and other patches (religious knot, world conservation, etc.) spaced across the top. Put picture mounting brackets on the back for hanging on the wall.
Place PW derby car, raingutter regatta boat, space derby rockets on the shelf.
It's a lot easier to make than it sounds. Cedar is soft so you can use a hand saw if a table or circular saw is not available. You do need a power drill for the pilot holes for the screws, though. I made all 8 (undecorated) in about three hours using a table saw and power drill.
Let me know if you're interested and I can clarify the instructions.
I also had my den make very easy but nice looking displays for thier Space Derby rockets.
