Panama Pacific International Exhibition, Part 1

This is my grandmother's season ticket to the Panama Pacific Exhibition in San Francisco, 1915.
She was 22 in 1915, with three children, all boys. Her oldest son was born in 1913, my father and his twin brother were born in November of 1915. She told stories of pushing the twins around the fair in their double stroller!

There are no tickets out of this book, but most of the tickets from my grandfather's book were used. Hopefully this post will be followed in the near future with a scan of my grandfather's book, too, along with other items from the PPIE.
