More images and links to pictures other people have taken. For commentary on the private tutoring classes that these posters advertise check out my older blog post.
Motondoso has a interesting photo that was featured on Kottu.org of a collage of poster scraps on Sri Lankan walls. So common that we don’t notice it.
Victoryrock has a similarly artistic image of tuition class posters from Galle that has poster.
Both much better that the crude “documentation-al” images below.
