A List Of Things Thrown Five Minutes Ago

FOILED: So, I headed out again with the remnants of the Hoeffel '04 campaign for our shot at glory in Quizzo Bowl 3. If only we had a former Who Wants To Be A Millionaire stud on our team, we could have placed better than our 6th place (out of 50+ teams), and though we aced the entire "Chicago or Indianapolis?" round ("which was founded on the White River in 1821?"; "which is the home of Kiwanis International?"; "which hosted the first controlled nuclear reaction?"), we could have used some help on the following, each of which we got wrong:

• Which bombshell's image was painted on the first nuclear bomb tested after WW2?
• In what country was Mata Hari executed?
• What team has won the most NFL championships? (note: not Super Bowls)
• Indianapolis is the second-largest state capital city, based on population. What's first?
• What artist, who would have turned 113 today, painted "The Problem We All Live With"?

No Googling, because it's not like we were allowed to. Hardest one I got right (IMHO) -- which of these Philadelphia institutions opened first: Bookbinder's, McGillin's Olde Ale House, Pat's Steaks or Gimbels Department Store?
