Something for #MarbledMonday - a selection of marbled paper covers and endpapers I'm encountering as I accession and catalogue old ledgers, historic corporate records transferred to Archives last year. More about the contents and arrangement later, but for now an unexpected array of colours and patterns from the carapaces of otherwise mostly prosaic codices:

This one looks to me like the patterns made by sunlight through water over rippled sand.

I'm surprised how very worn this inside cover is.

To see larger images, right-click on a photo and select 'open in new tab'. Then to magnify further, click on the image if a little magnifying glass appears.

Well, there's no getting around it, this one just looks like salami.

Classic red nonpareil pattern - very common but no less one of my favourites.

This looks like a moonscape - made of green cheese? The bumps are from water damage that has caused distortion in the pulp board underneath.

More of same water damage here.

Spectacular bright colours on black - like fireworks.
