Jon's correct, it's Lattof - Zone 11 Dealer 327.
Lattof took a GM buyout in '08 after 72 years as info @ this link...

The ads are w/ the old newspaper groups which require subscriptions, NewspaperArchives or Newspapers.com who have the most stuff but your system needs to be compatible or results won't show.
Some stuff from the Archives is accessible free via Google as Wickham ad above, I gave a few quick tries for Lattof but most results from the 50's/early 60's although something may be there w/ more thorough searching.
It's unlikely yours is but we found a few Member cars ads in this thread a few years back, give it a whirl and good luck....
