Marvel recently ran a poll for fans to pick the Top 70 Marvel Covers
to commemorate their 70th Anniversary. Shellhead had a decent showing, nabbing two spots with the classic "Demon in a Bottle" cover (vol. I #128) coming in at 59 and the "Hulk Behead Shellhead(less)" cover (vol. IV (?) #19) coming in at 67. Tony also appears on another eight covers. A pretty fair representation of our Armored Avenger, despite the relative skew toward covers from the past 20 years.
