Noticed the link you posted for the olympic stadium and checked out the picture; we are waiting for Bobitutu to post a translation of the message that came with the original drawing of the building or bridge and the aircraft. There was a description or reference on a previous post, something to do with TWO BOWS...that fits with the stadium, if you think of a BOW as in RAINBOW.
Sorry I don't know how to post the photograph...will someone please do so?

The first mention of 'two bows' I can find on this thread is 1651 by all4one and BagCamAddict posted the picture of the stadium on #1662.
HI Fred,
Been watching you for a few days I like the way you think. Hope you stay around:)
