Dear Philadelphia Map Society,

Our visit to the The Brandywine River Museum is of course cancelled. We hope to select a new date when things have settled down.

Muriel Fitzpatrick has shared these map sources:

This is a terrific story about maps. I thought you would enjoy.

By the same author. I wish I had seen more of the Humboldt events in the city this year.

I also saw a presentation by the author of this book. It has the same theme involving a quest for information after the war. I'm not sure how intertwined the stories are because so many agencies were involved in the enterprise.

Be safe and take care,
