Thank you for contacting the History Hub.
We recommend reaching out to our Cartographic Department to request a search of their holdings for the maps you are seeking.
One area of research that may be of interest is the historic Sanborn Insurance Maps. The Library of Congress has a very large collection of these maps digitized on their website and we found several for the Malden, MA area from various dates. https://www.loc.gov/collections/sanborn-maps/?fa=location:massachusetts%7Clocation:middlesex+county%7Clocation:malden
We hope that this information has been helpful and good luck with your research.
