Fighting ignorance since when?

General Questions
#1

I don’t know if this should be in About thin message board, so mods feel free to move it but

What was the original slogan of the SD and when did Unkie Cecil first use the “Fighting Ignorance since 1973” slogan?

Thanks

I’m assuming not before 1974.

If I recall correctly, Cecil’s first slogan was along the lines of “My God, can you believe how stupid these losers are?”

But this one was never on the masthead.
