My mother collected rabbits. When she died, we lined them all up and took a "family portrait" of them all, then put each one in a box and mailed them to her friends and family so everyone got one. Or more. I see a possibility for many photos shoots in your future, featuring your grandfather's beloved owls in various situations. Do you follow @cjphoto? He's very clever in his use of objects to set up studio shoots.
@jyokota - Thanks for introducing me to another clever 365er, Junko!
