Since this is a reproduction it should not be labelled in the manner of an original work of art. A more appropriate title card would be:

Reproduction of "Name of Original by Artist's Name, Date of Original, Original Medium"

You could use the method of reproduction in place of the word and citing the original medium is very optional. You do not want to confuse the viewer into thinking that the work at hand is in anyway an original piece.

Of course, even as a family member, if you are not the original artist (ie copyright owner) you will need to have that person or their estate's permission to publicly display or sell the prints.
