Double Dragon Easter Egg - Hidden Initials

At the end of stage 1 where you fight the Abobo (the mutant strongman that looks like a hydrocephalic gorilla), a crate in the background has the initials "TJC". Also in the beginning of stage 2, the box that you can pick up and throw has these same initials (provided you are facing torward the right side of the screen; otherwise it's reversed).

It took me a while to figure out what this meant and thought I'd have the beat the game and look at the credits to find out, but then I accidently hit the "RESET" button and saw "TECHNOS of JAPAN CO". Now I know what it means. :)
