This is an ad for two early releases by Tecmo for the NES, Mighty Bomb Jack and Solomon's Key. This advertisement is from the February/March 1988 issue of Nintendo Fun Club News.
Mighty Bomb Jack was released by Tecmo for the NES in 1987. I always though it looked like an interesting game but reviews were generally poor. It seems to be a pretty generic platform game and it was apparently fairly repetitive and without much depth. Despite this, it has seen numerous re-releases. It was released for the Wii Virtual Console in 2007, for the 3DS Virtual Console in 2012 and for the Wii U Virtual Console in 2014. Those also got rather poor reviews. More contemporary releases include ports for the Commodore 64, Amiga, Atari ST and Game Boy.
Solomon's Key was originally an arcade puzzle game released by Tecmo. In 1987 and 1988, a number of home ports were released. In addition to the NES version, there were ports for the Amiga, Atari ST, Commodore 64, DOS, Sega Master System (Japan only) and others. The NES version of Solomon's Key was released for the Wii Virtual Console in 2006 and in 2013 on both the Nintendo 3DS and Wii U Virtual Consoles. It was also released for the PS4 in 2015.
These games aren't really the ones that made Tecmo famous on the NES. That would come later with the release of Tecmo Bowl.
