Thanks, Eric. I printed it in 59 x 78 cm (with my company's plotter, but pssst, don't tell anyone   ) and stuck it to a door. Since you're the expert I have a question about the map: In the drawings of the June/December solstice, the white area represents the sunlight. It has some kind of oval shape, but it's definitely not a circle. We see the sun as a circle from the earth. If the sun was a ball or a circle, the projection of its light would be a circle. Something doesn't seem to fit here.

How was the white shape (sunlight projection) measured? I could only think of a gigantic experiment where thousands of people in different parts of the world note the time when the sun is up/down on a specific day, and someone would have to review all the data so he/she can build a map from all those coordinates. In today's world this doesn't seem too complicated, but back in 1892, when the new standard map was created, without internet and cell phones?

David Rumsey Map Collection
An interesting collection of maps on archive.org was created since the 6th of January 2022.

Well known map (for some) uploaded since March 2022 in the above mentioned collection. I never seen it this detailed, so thought to share it here.
Composite: Tavola 1-60. (Map of the World) (with additional spheres and labels in the four corners).

I found a descriptive key included with the Gleason's Map addressed to his students.  The Projection of J.S. Christopher.  He talks about the sun's altitude and mentions, "the sun is always seen at an angle of 45 degree arc in the sky, just 45 degrees either latitude or longitude from its daily path.  He wrote, "there is no method known by which an angle of 45 degrees can be produced from the 4 quarters or cardinal points of a sphere or circle, without placing the sun in just the relative distance from the earth or circle that the above geometrical diagram places it."  His last remark is, "the earth is a globe or a plane, take your choice."   I found it at the Yale Library Archive.
