Review for LEGO set 5900 Adventurer Johnny Thunder from Brickset
“Johnny Thunder was widely available throughout the other sets in the theme, but as an introduction to the Adventurers theme at a very low price point, comparable to the foil sealed minifigures of today, this set at the time really fulfilled its end of the deal. It provided a... More number of new pieces, a minifigure and sparked an interest in the Adventurers theme as a whole.”
