Anyone know anything about these ? Seem to be new for 2017 and show historical images. Not sure who produces them, but I have seen "you know where", numbers up to 8.

Backs say promotional prototype

1- George Washington
2- John Hancock
3- Thomas Jefferson
4- P.T. Barnum
5- President Donald J. Trump
6- A New President
7- Constitution of the United States
8- The Civil War

Apparently these are part of a full blown card set, which came out in April.
