"Do you have Prince Albert in a can?"

"Well, you better let him out!"  Or so goes the prank call that kids supposedly used to make to tobacconists back in the day.  Ah, the days of easy laughs!
The brand was introduced by the R.J. Reynolds Co. back in 1907, named for the Prince who later became Edward VII. Apparently, according to the can, the process by which this blend was discovered was quite scientific.
