My grandfather, James Pendelton Waggener II, passed away March 12, 2010. In his belongings I found some samples of graph paper he used in college between 1939 and 1943. Most of the sheets are on very nice vellum. I don't know if you can still get sheets like these, so in the hopes that they may be interesting to someone, I've made some 1200dpi scans available below. No guarantees on the color accuracy.
