Pointers to look for in buying and determining suit ages

[esteban68]

I am new-ish to this game and would like a few pointers into determining authenticity, age and styling of vintage suits.
Has anyone got any picture rich articles or book recomendations...I know there is plenty on here but I could do with some newbie advice, I already bought an aledged early 50's suit and posted that on here on the British suit thread (I am still trying to get a decent local tailor)but have had little feedback.
