Yes, but signed may mean a printed on signature because this is a print. A print may also be actually signed by the artist but that should be noted in the description.
A print is a copy from the original painting. If the original painting was signed by the artist, that signature will show up in the print. What needs to be determined is, is the artist's signature in the print or on the print? If it is in the print, no additional value would be attributed. If on the print, then the artist has actually written his/her signature after the print was made. This may or may not add value to the print.
