'Executive Blockhead' Party Game (1970)

“Executive Blockhead” party game in original box from 1970. The goal of the game is to add blocks to the tower without having it collapse on your turn. Instructions are missing but we pulled these from the internet. It’s similar to Jenga:

The first player sets one of the blocks on a flat surface; this is the only block allowed to touch the base. Each player then takes turns adding a single block until the tower collapses. The player that knocks over the tower on their turn loses. A player who loses three times is eliminated. The last player remaining wins.
