Dear Patrick,
DBpedia 3.9 is based on dumps from April 2013.
A snapshot of this museum at that time is the following
https://en.wikipedia.org/w/index.php?title=Museum_of_Mathematics&oldid=542248551
and at that time no picture was attached to the page.
The next release (in the following weeks) should include this image.
Best,
DImitris
