my copy of TMoST is too old to look at without fatiguing it more.
Mine too: waterstained first ed., first printing: cover has small E model in the blue sky of Yesterday is Tomorrow, and K/S with pink back ground: Empath maybe? Ep guide in back only goes thru S2.
What a great book when I was a kid. Also still have Gerrold's Worlds of ST, which was above me at the time, but still very insightful about drama and writing, now that I get it.
God, I got both of those still to this day. My Mom got them for me around 73 or 74 when I was is elementary school.
