I have never seen these in person and would go inside out to get them. I’m guessing there is also the good Doctor and Vanda as well, these are the only pics I’ve come across though
*edit: Thanks Mini for reminding me about the video, you can see it on the LU website or on Ethan’s Vimeo stream:
Here’s some screen caps of the promotional tiles from that video.
Here’s some more interesting LU promotional artifacts. These were on display at E3 in 2010, going by the flickr set, and the photographer was schooled by commenters by the looks into revising his descriptions. I have no idea the fate of these ~beautiful~ objects d’art and have a hunch that Steve might have seen them in person? Images link to biggified versions.
