Display submission history of a node? Use case: This content type offers an Approval Status with three radion button options, Submitted, Approve, and Reject.

A node from this content type can go through all three in its lifetime. 

And that "history" should be displayed at the bottom of  the page.

How do I do this?
You will need to make sure that the content type creates a new version with every edit. Then, you should be able to make a Views block that shows node versions and the status field.
