Challenger drawings, sail plan

[TomY]

Another scan done in two pieces and blended together. These old pencil lines still snap into a very nice design.

It was mentioned on another website that posting the scans of these Alden drawings could be in violation of their copyright. Hmmmm.

I'm not sure, these were sold to me without any stipulations (that I recall, it was several years ago) by Alden. Of course in my interest to simply help preserve the old boats and not build and sell them, I can see no harm. Anyone have any thoughts on this I should be aware of?
