1964 Lancaster book

I was in a second hand book store yesterday and acquired a 1964 copy of Bruce Robertson’s
“Lancaster – The Story of a Famous Bomber.”

Although ex-library with a few tears and rough edges, a very good read that I thought covered
history of the aeroplane very well. My question is this considered a fairly rare book as it seems
to contain all the facts and photos sort after by aviation buffs like myself.
