Am trying to find movie "Luana", starring Glenn Saxon and Mei Chan,
directed by Bob Raymond.  Or the poster advertising "Luana"

I have found a place that advertises this movie in NTSC format for
$25, condition good-to-very-good.  The site is at
http://www.aflam.ws/index.htm
Select on-line store, and then Tarzan Girls (on the bottom line of the
list).

The movies are listed alphabetically, so scroll down until you get to:
