Hey, this looks interesting for the right person:
173 Slides Airstream Trailer Collie NY Worlds Fair '64 - eBay (item 160271824956 end time Aug-19-08 19:58:01 PDT)
it is a collection of slides from a prize-winning collie owner as they travel about in their Airstream.
" ...Follow along with the couple as they take their dog - er, I mean Buzzy - on cross country trips in their Airstream Trailer. If you love Airstreams and collies - this is your lot!..."
you can see a pic of the collie with AS and an AS rally photo at the eBay link above.
and the usual disclaimer that I have no connection to this in any way other than stumbling upon the above applies
