A little leaflet I found tucked inside a second hand book that I bought a few years ago.
Sadly the organisation no longer exists, but there is no reason that you can't promote, and carry on the tradition yourselves.
For some reason unknown to me the image keeps flipping to the horizontal when I copy it to here.
The second image is a close up of the corner.
p.s. If any of the moderators have the facility, could you try orienting the first image correctly. Cheers.
