How about the 40th Anniversary DVD set of Woodstock? If you bought it at Best Buy you ended up with 2 additional JA performances- 3/5 of a Mile and Volunteers, in addition to Saturday Afternoon and Rock Me Baby.
A somewhat rare item I have is the music songbook to After Bathing At Baxter's...they weren't cranking those out as much then as later in the 70's.
Or, you could just go buy that Grace Slick's worn Monterey dress on Ebay.
