Suggestion list from a few pages back so we can work from it.
1: The Battle of Djibouti, as suggested by Byrd. Googer and I are flattered as fuck.
2: Viktor and Juhani anything. Seriously, the importance of that story line in the development of what PoW became should not be understated.
3: Canadian beach landing in Cali. Not a serious scene, but still fucking iconic.
4: Assassination of Tejero. Big scene, fairly momentous.
5: Battle of Milan. Probably the most enjoyable pre-Spanish-Ethiopian War battle in the entire RP. Tanks circling the palacia or whatever that building was called and tearing it all to shit.
6: Though the big China scenes are pretty well covered by Aaron's art, the general ambience of the Chinese Opera captures a lot of China in one swath, in terms of setting and important characters.
7: To me, Spain's iconic image is wealthy people and politicians partying on zeppelins above Madrid.
8: Sevan. I might be partial to Sevan because I spent so much time writing there, but I think it deserves a little art.
9: I don't even know if this is canon anymore, but as it strange as it sounds, the Spanish and American battle during the blockade of Boston is iconic to PoW for me. An African agent watching from a telephone booth as Spanish and American ships duke it out in the distance, and a New English freighter chugs forward full of near-privateers... I dunno, I think that is a great symbol of early MCF precipice really.
Or, I guess alternatively some mix, though that might be ambitious.
