Alphabet Anxiety

I'm working on a birthday present for Jake - an alphabet book made up of photographs.  I've been meaning to do it for the last two birthdays.  I figured I better hurry while he still has a couple of letters to learn.  : /


I'm getting so desperate, that I'm at the part where I'm putting him in front of props to complete the alphabet.  Today, we went to visit his good friend Thomas the Tank Engine so we could take a picture in front of the Railroad Crossing.  I asked Jake to look at me when Thomas came chugging by. 


Instead, Thomas came by, he turned to look at him and said "cheese!" to Thomas. 

And then I had to settle for the cheesy smile.

I'm at a complete loss for the letter "V" - any ideas?
