What tissue and preparation were used for CMU-1 open slide example

[David Clunie]

Hi all

I am working on my TIFF (SVS) to DICOM converter and I was making
some samples that populate the specimen preparation description.

Since, like everyone else I start with the openslide CMU-1 sample,
I was wondering what tissue and anatomic location were used for
that slide.

Does anyone know/remember?

Thanks ... David
