things learned from the foreword:

• Anne was from Frankfurt am Main.
• Otto (her father), the only survivor of the family, was the founder of the Anne Frank Fonds.
• Anne wrote in a cute, not at all neat, rounded ball-and-stick roman. Pretty similar to my own handwriting, come to think of. The page shown as a sample has a smaller note taped to it; this note has some cursive exercises at the bottom. (At least I think they're exercises; they're hard to follow for the non-initiated, likely an equivalent to German Kurrent, but most letters in the two sample lines seem to be single or in pairs.)

I spoke too soon; there's a facsimile of her list of pseudonyms on p.14 and it's all in cursive, showing comfort with the form. It's a pretty readable cursive, to, way more than the note I mentioned above.
