I have these charts posted on the free give away site here on cloudy nights. Right now there seems to be no interest.

Most carts are for long period variables, recurring nova , u-gem stars , and a number of others, 

Some charts are the old blue print, but most are white charts.

I f you are interested go to the free give away site.
if no takers I will trash them soon.

I don't think that those are useful any longer for photometry since the sequences have all been updated from what they were then (up-to-date charts are printed on demand from the AAVSO website these days).  Their real value is in their historic nature-- instead of trashing them, contact the AAVSO and see if they might be interested in getting them -- many organizations no longer have copies of things that were printed in the past.

Agreed that their value would  be historical or nostalgic since the sequences have been revised and updated.  Did these once belong to an observer of note or have any notations, etc. on the back or the front of the charts themselves?

Tim. I obtained these charts directly from the AAVSO When I joined in 1974. I was given a few free. the rest I had to pay for but at a minimal cost.
