What is a good gift to send to an elderly couple in a nursing home?

I always send my great aunt and great uncle, in their 90′s, flowers for every holiday (I live 2 states away from them). I’d love to send them something besides flowers but I’m not sure what is appropriate.

I agree with the pictures. Be sure to put labels on the back typed in big font who everyone is (and maybe is descended from) and where the picture is taken. Size 4 x 6 pictures at least and maybe include a magnifying glass although they probably already have one. Or a box like an old lidded box that’s hinged to hold them and future pictures.
You are a very thoughtful person to be sending them presents!! They are lucky people!
