This is comic is Edgar Rice Burroughs' Tarzan,  #136, published by Gold Key in July 1963.  It is showing its age, with yellow pages, creases, minor tears, and the effects of being read, handled, stored and moved. It's missing a corner of the cover, with a number written near the top.

I am not a comic collector or dealer, just selling some things I have had for a very long time.  If you have any questions, let me know.
