Larry,
The emblem carried on the Ju 88 is that of the 3.(F)/33. A brief illustrated history of the Staffel and how the emblem came into being (obtained first-hand from its designer) is featured in my forthcoming book.
However, because of space limitations, the balance of the history, information on the unit's aircraft and personnel along with other relevant material, will be added to Andy Mitchell's site at:
http://www.luftwaffedata.co.uk/ later this summer.
I do have a copy of the photo which was posted on eBay and although the aircraft has been tentatively identified, I am currently corresponding with surviving Staffel personnel to see if we can come up with a positive ID for it.
Regards
Dave
