Until recently, the 7 known Postcards from the George Mullin "Billie Jones" Postcard set were, as listed on the VintageBall site:
1. At Bat
2. In Action
3. On the Bench
4. Ready for Action
5. The Tiger's Favorite (not pictured on the site)
6. Sitting on League Ball
7. Throwing Spit Ball
That leaves 3 until-now (?) unknown Postcards. Why do I say that there must be 3 more (for a total of 10)? The 6/28/1909 edition of the Indianapolis Star included the following ad for the sale of Billie Jones' Postcard set of George:

I am posting the 3 remaining of the set with photos below (along with the "Tiger's Favorite" referenced above). They are:
8. Little Daughter Showing Him the Pennant
9. Showing Different Positions of Throwing
10. Geo. Mullin (in a suit)
Hopefully, the Tigers and Postcard fans will enjoy. Not to mention, George Mullin was a beast on the mound! There have to be more of these out there. Hopefully, more will come to light with more attention.
