This week - A Real Mobile Tank (1959) Dear God in heaven, I don't think it gets any better than this. A tank for $4.98 ($31.81 in today's $$) is a deal that even the Russians wouldn't give Castro on his deathbed.
Check out the text for this beastie. I like the "real periscope permits you to see the enemy without exposing yourself". hmmm. Maybe Micheal Jackson should have purchased this.
