I voted before reading all the posts. I WAS influenced by the fact that the balloons looked like eggs...and because I like the way the color scheme stands out from what already exists.
I like what MonicaT had to say, should be an egg for every year!
P.S Just flip those balloons around and put...
#2 because it stands out from the others as a 5 yr. achievement should. I'd have like to have seen some chicken themes in there though, like a rooster crowing, 'cause 5 yrs. is something to crow about!
