The reason ebay gave for the removal of the auction:
Images depicting high ranking Nazi officers are not permitted to be sold on the site. Please do not relist this item.
We recognize the historical significance of World War II and that there are many militaria collectors around the world. We allow some related historical items, but ban others, particularly items with Nazi markings and items which may be considered Nazi propaganda.

Interesting… If you search ebay for “Hitler Shirt” there are around 100 results. It appears that lots of times ebay has trouble enforcing their own rules.
