Posters for grandchildren

I've been wracking my brain as to what to send  to my grand kids for Christmas.  I've been the book grandma, but as they get older not all of them have developed a love of reading.  Big SIGH!!! Some have developed a love of drawing which is almost as good and I have sent drawing supplies to some.  I don't like to send toys especially trendy toys because I want to send something personal that can help us relate to each other. All books get read by me before they get given as gifts so I know they are appropriate and we can discuss them.  Of course with drawing we can share our current projects but I still have a couple of kids that kind of baffled me this Christmas.  Then I came up with the idea of the zoo collage.  I do not live close enough to take them to the zoo in person but I can take them to the zoo through my photos.  I am going to have this blown up to poster size so they can put it up on their wall and remember me.  I find it hard to be a long distance grandma and any ideas would be appreciated.
