He knows a lot about those stars, from how many there are on each block, to how they tend to fracture from wear. An easy way to tell the original stars from the modern ones is to check the brass names - the originals have raised letters, and the more recent are set flush.
The newer ones tend to crack more readily as well, because they are thinner. They crack along the base of the points, or right across the middle. He said that Jay Leno’s star cracked three days after they unveiled it, and it took several replacements to get one that would last.
The only person working on them, he cleans the stars in rotation, and when he finishes them all he starts over again, and does several rotations a year. Sixty four stars on a short block, 128 on long ones, and a max of something like 164 on the longest stretch of road, or something like that.
They add a couple of stars each month, but you can still see scattered blank ones here and there saving spaces for future stars.
Which he will clean.
