Speaking of moustaches...
My father wore a moustache all his life, certainly I never knew him without one.
Legend has it that he lost it once in a poker game. It's the only time my mother saw him without one, and it didn't take long for his look to be reestablished. (I don't know if my siblings existed yet, but I imagine they'd have been too young to remember.)
I have one photo of him sans moustache, age 17, but I don't see the resemblance. It was taken by an army buddy, inscribed and dated on the back so I know it to be him, but he looks a stranger. Indeed, it troubles me to look at it.
There are a few other pictures from his youth — but he was sufficiently angled, the photos grainy and shadowed... The effect is such as if the moustache were there.
Here's a school photo from childhood (circa early 1930s, Poland now Lithuania). That's my dad at the very front, the one on the left, looking very much like the man he grew up to be. He's, well, moustached.
