Finished reading The Blue Lotus, and was reading up on Herge and his interesting history with racism. These are some excellent essays: 

Can the Subaltern Draw: The Case of the Arab Henchman by Nadim Damluji

Tintin in Otherland by Alex Buchet 

This is unrelated to Tintin, but Nadim Damluji’s essay about the orientalism in Craig Thompson’s Habibi is also excellent and sums up my thoughts about it more eloquently than I ever could in my own words.
