Some people might know, most won't, but the website of the Rijksmuseum, the Netherlands had an overhaul. Most fancy about this is the overview of their archive, which includes a lot of high-resolution type and lettering material. It is a bit of a search, but there are some real gems to be found and is perfect for lazy browsing on a lazy sunday.

Next to this, I wonder if some people might know of the origin of this type:

It's used by Johannes Enschedé around 1760 as a companion sheet to an etching.

The gallery is easy to browse and filtering is quite simple, which includes filtering on colors and techniques. The english version sadly doesn't translate the keywords, so that's a bit of a drawback.

Much can be found at:
