Justice League of America #31 from DC Comics
I still remember this being the first Justice League book I ever bought.  I was at a comic show and I found it in a quarter box and my cousin told me it was worth some  money and I should buy it.  So I did and the proceeded to read it.  I was hooked on the JLA after that.
