Dear Mark –
It surely has been a long time since I’ve written you and about that long since I’ve received a letter from you.
Mother often writes me that you are still working on your airplanes. I just wonder how many different planes you can identify – The P-38 of course is easy – the P-40 isn’t so easy – How about the F47, F4U, F67, TB7, SBD, the B-25, B-24, B-17 & the Ventura? I think I can identify each of those types – How about you?
I hope your school work is coming along fine by now and I know your grades will be as good and probably better than last year. You can do it I know. So I’m looking forward for a good report at the end of your first grading period.
Well son I’m betting on you so don’t let me down.
Love Daddy
P.S. Don’t forget that kiss to Mother from me.
Mark (January 1943)

Who knew there were no many different kinds of military aircraft?
That’s one of the best photos of Mark. 🙂
I have seen a great info graphic poster that was created during WWII. I think it is British. It has silhouettes of allied planes vs Nazi planes so if one flew overhead, a person would be able to tell the difference. I think that would be very important in places that were under risk of being bombed.
