I have an old 914/6 blueprint.
Not sure of the authenticity and where it came from, but, I know I bought it over 20 years ago from Jacques at l'art et l'automobile...way before any scanners.

This thing is large, 33.5"x47"...similar to the one described on Pelican Parts:

I have never seen another one of these in this dimension, and the print is very crisp.
Great shape, no tears, edges are all nice, just didn't unroll and photo as nice as it looks.
Thinking $200 + shipping? Offers?
Or maybe someone here can chime in on the availability of these?
