A great Christmas gift for your grandma who likes contemporary art would be a membership to a contemporary art museum, such as the Museum of Modern Art (MoMA) or the Guggenheim Museum. Another idea would be an art book featuring the works of her favorite contemporary artists or a framed print of one of their pieces. You could also look into local art galleries in her area and see if they have any exhibitions or shows happening soon that you could take her to. Lastly, if you want to go the extra mile, you could commission an original piece of art from a contemporary artist that she likes, or get her a gift certificate for a custom art piece.
Or you can get her a star map with an important date you share.
