My dad turned 70 last year, and said he didn't "need" anything. I found an old slide that was his favorite picture of myself and my sister from when we were little girls, and took it to a photo lab. I had the slide scanned and then made into a proper archival print photo, and framed it up for him.It was a hit with the entire family, and Dad keeps it on his desk in his study.
A framed photo of you and your dad when you were a little girl might be perfect. I also like relache's idea about you and any siblings. Photos are always wonderful things to receive and give!
Wonderful gift, relache. Another great gift idea might be to get a watch or pen set, then engrave a personal message to him on it. It's the message that will end up being the gift.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
