When Erich Kästner and Hans are sitting together they make up a story about how only parents of twins should be divorced, so each parent can get a child and they can switch places. This story later became Kästners novel "Das doppelte Lottchen" (Lottie and Lisa), released in 1949 and was the source for "The Parents Trap".
It doesn't matter if a story actually happened like that or not as long as it is true.
The signature that Erich Kästner gave a woman on an autograph picture is different that Kästner's actual signature. However in the signature Kästner was writing into Hans' book is the same as the one of the real Kästner.
