will have a guess at the connection all presidents that have appeared on postage stamps
Names correct.
Not the connection I wanted. ? 
presidents who owned slaves then maybe
Sorry. Not the one
ok will have another stab at Vice presidents who went on to become presidents
That’s the one
They’d all been serving Vice Presidents before becoming Presidents
Edit…Well done Feey!!
Correct but Feey just pipped you at the post. 
4 and the connection
