You can find some vintage logos at
www.logoserver.com.
See MLB-AL and MLB-NL sections.
Or post on Cuss16 graphics website. There are 4 or 5 guys who might design you some very nice logos. List them 2 at a time for the quickest results. When they do those 2, then list 2 more.
Sorry, the website address I had did not get me to Cuss16 site.
I'm sure he or someone else will post the correct URL for the site.
