It seems to be a lost art in the modern era of decompressed storytelling, I'm referring to the single issue "done in one" tale that ensured that you received value for money from your comic book. Back in the Bronze Age distribution was patchy and tracking down consecutive issues was a tricky business so reading a well crafted single issue was a welcome treat. One example that sticks in the mind is Justice League of America #109 (January/February 1974).
