This challenge feels interminable but at around the 70% mark, a new postcard arrives:

The postcard begins by telling me:
I would be remiss not to spend a bit of time talking about Bengal tigers in India. These magnificent and powerful animals have dwindled in numbers, largely due to poaching, habitat destruction and human-tiger conflicts. The plight of these beautiful animals has reached such proportions that it now has its own international day on 29 July of each year. Its purpose is to promote the protection of the tigers and their natural habitats.
The tiger is India’s national animal and the country has proactively engaged in tiger conservation since 1973. Home to 80% of the tigers in the world, there are less than 3,000 of them left in India.
