sorry for bumping such an old post, but this is still one of the top search results online for "Marion David Pettie."
Just wanted to note that his image can be found in this book:
books.google.com...=snippet&q=finders&f=false
on page 152 (it's even viewable online). It's not very easy to see, but I'm sure the printing in the actual book is slightly better than the
preview.
