Please Help Identify

Travis George

This is my first post on this forum. All help is greatly appreciated. I have many stamps of this era but this one stands out. It doesn't have a denomination printed on it and it is postmarked. Is this an error stamp. Cannot find one like it anywhere. Thank you for looking.
