I found this example of optical sizing for “logos”, from Enschedé 1825.
Did I see this used in another presentation/blog about optical sizing already? Or maybe it was some other similar example?
This is also from Enschedé, but about 100 years later, showing manicules at different sizes.
I think the example I had in mind showed manicules with different levels of detail for each size? And maybe a comparison with emoji/icon details at each size? Hmmm
