Welcome aboard!
It's nice to see a new, fellow HOF collector entering the hobby, or at least the Net 54 Baseball world. The below link should prove very helpful for you:

To answer your question, the first individual card picturing Barney Dreyfuss is from the 1910 Tip Top Bread Pirates set. Although the condition is not the best, here is an example of what it looks like.....
If you need any help or have questions, I have been collecting these for nine years now and would be happy to help you as much as possible.
BTW your post should be on the main board section of the website rather than the B/S/T section. Hopefully, Leon will move it over for you.
