The document discusses an attempt to collect images of all 51 Space Invader installations in Bangkok, Thailand. The author has found images for 389 out of the total, but is missing images for 8 installations including BGK_x1 and BGK_x9. They provide a list of installation codes and reference links to help locate the remaining images.

2. Bangkok has been one of my main challenging quests.
As you see I am missing many of the invasions. I have 389
images (out of 51 invasions) and 8 are not even referenced.
I could not locate a few and maybe you can help me.
These are BGK_x1, BGK_x9.
Your help would be much appreciated!!
