On ebay,,anytime you are not sure,,just put a question mark after the word !! And list both options !! Similar to this,, Joe Namath by Leroy Neiman,, Lithograph ?? Print ?? !!
Then describe it !! That would let any one interested know that you are not sure !! If you just tell them,,they will understand !! Buying a litho and then finding out it is a print,,might not be good !!
