The first edition came out in 1977, then a revised version in 1982. You'll find a copy on the shelves of most mathematical physicists. The acknowledgements page features this fanciful drawing of the three authors riding what I guess is the snail of real analysis? Whatever it is, I love it. (14/n)

The acknowledgements page thanks several people for proof-reading and typesetting the manuscript. At the bottom is a fanciful drawing of the three authors riding a giant snail through a garden. The snail has epsilons and deltas written on its body, and there is a spiral along its shell featuring the repeated word "manifolds." Butterflies flutter around them.

Cécile worked on whatever she found interesting, and she was famous for having a seemingly inexhaustible supply of thesis-level problems for curious students. (15/n)

She had a "problem drawer" in one of her file cabinets — it may very well have been one of the drawers visible in this photo from the first tweet. When Cécile met with a new student, she'd pull something from the drawer for them to work on. (16/n)

Black and white photo of Cécile from the first tweet. She is wearing a floral print shirt and smiling at the camera. A blackboard and file cabinet are visible in the background behind her. I think one of the drawers just visible at the left edge of the photo is the one with her "problem bank" of thesis-level problems.
