Can't pull docker image that I pulled many times before

I have a docker image in my docker hub account that I downloaded many times, but I did not download for over a year.

On a brand new mac, I attempted to pull my image, after logging in via terminal, and I get this message:

Error response from daemon: repository / not found: does not exist or no pull access

Has anyone received this message in similar circumstances? I could pull a new ubuntu image just fine. I pulled this image from docker hub many times, but a long time ago.

I’m running:
Mac OSX Sierra 10.12.1
Virtual box
Brand new download of Docker-Machine, Docker, via Brew

My image is fairly large, at 7GB.
It is an ubuntu image, created nearly a year and a half ago.
