Have the image scanned and post it up on a site somewhere. The family will surely see it.
As recently discussed on here a young fellow i knew recently passed away. A very large part of the funeral service was video presentation of material which had been uploaded to the net.
Words, images, videos, much from folk Dane never even met where used n the service. And they were greatly appreciated by the family and friends, immensely appreciated.
To be honest in this day and age its more likely they will see a digital version of the image than a paper print.
