This question already has an answer here:
I'm trying to get alphabetical labels (a, b, c, d, ...) superimposed on to a series of Mathematica plots to put into a $\LaTeX$ document. Ideally, what I'd like to do is to add a label to the first graph with "drawing tools" so I can set the size and position by hand. Then somehow to access the size, position, etc. of this inset graphic so I can then automatically add the labels for the other graphs.
