History of The Beatles as told by their hair

I'm not sure it is super accurate but this poster sure made me smile this morning.
What do you think, which year was the fine lads' best in terms of hair style? My favorite is 1968. Although I love the bearded Paul of 1969.
Have a lovely day friends! xx
