OT 917-30 Sunoco Promo Kit

[URY914]

This is off topic, but I got no replies on the Classic Porsche Literature BBS so I thought I'd re-post here.

I have a Sunoco promotional kit from 1973 for the 917-30 in very good condition. My father knew someone who worked for Sunoco at the time and they gave it to him to give to me. It is a full color glossy folder with inside pockets with loose pages of specs and info. I far as I know this was only distributed in house and not available to the public. I have never seen any others like it.

I also have some news letter type material which Sunoco put out during the season that has pictures and race reports. These are in black and white and printed on both sides.

I don't want to put this stuff on E-bay to have a bunch of wahoos looking at it, but I would like to know what is worth.
Anyone know? Thanks
