Larger/better version of rare old photo of Cheryl Tiegs

We're looking for a larger and/or better version of this rare photo of Cheryl Tiegs that's probably from an old magazine of the 1960's.....

We're also interested in any other photos that might exist of her in the same clothing, or in very similar poses that expose her stomach/belly in similar ways.
