Here's a precursor to Kafka attaining immortality -- it's a Kafka in English Illustrated, 1890.
"Why did Kafka not ask to have his physical body—like his body of work—burned? Perhaps he realized that the annihilation of his corpse would not save him from immortality" (J. Zilcosky, Kafka's Travels, 2003).
