3.Ask finnish players rent some costume and roleplaying
(They may buy some clothes for children for birthday presents, and ask them to contribute)
lol - we used to have many pictures from an old live roleplaying session (and some people always got amused by them, I don't know why To sidetrack, in Finland we have many groups doing live roleplays in a rather artistical and serious manner - two weeks before the event each player receives like ten pages of text, describing the background, the personality and the aims of the character to be played; and also that character's relations with other characters. And then some general background information for everybody. People but a lot of energy to preparing their characters, and some people who have been doing a lot of it have become like talented amateur actors, effectively creating the atmosphere and drama of a fictional reality. I've seen people weeping and laughing in LARP sessions, having a collective immersive experience which generates a lot to talk about. So, for many larpers in Finland it is really a form of art. Yet there are many people who don't know that much about larping and they see it as purely childish thing to do. But for me it is more like a movie you can yourself take part in - a form of art which can be used for good entertainment or serious dept-psychological drama, or anything in between, and often a good mixture of humour and serious themes.)
Oh well, oh well. That was more than ten years since. And I see many of those people are still actively in the live roleplaying scene. They have yearly events with viking and iron-age theme.
So, it is more a case of disorganization from my side that we haven't yet arranged a new "let's take a portrait"-meeting with these good people doing iron age larps. We have some up-to-date pictures sent by them, but it would be super fun to arrange a proper live meeting just for purposes of taking tons of in-game pictures.
