What's the best way to render high-detailed @openstreetmap tiles in vector format for large format printing?
There are also sketches and pencil tests of several pieces, which reveal much of Escher’s design process.
@penguin42 unfortunately no... the https://www.foia.gov/ portal is wonderful for submitting #FOIA requests, although I did send a followup query via fax. Do you think they still use typewriters, too?
Updated my analysis with some additional NSA #FOIA ID's contributed by other searchers, it appears that the agency might receive an average of 6.5 requests per day over the past five years.
I believe the NSA might have a German Tank problem with the FOIA queue: the request identifiers appear to be monotonic integers, so my linear regression estimates that they receive around six requests per day.
#FOIA time! Or at least an acknowledgement of receipt... my other NSA FOIA request is going to be celebrating its third birthday soon.
