Atypical Soldbuch cover materials?

[landsknechte]

When I wasn't looking for it, I know that I have seen photographs of Soldbuch covers made from different materials other than the standard bark textured paper. Does anyone have any examples that they could share (especially for Heer Soldbuchs)?

Thanks,

Do you mean The Brown Cover where the pics were attached or a Cover outside the soldbuch to protect it?

The one where the pictures were attached.
