The file starts with the hex c5d0d3c6 (or ≈–”Δ as string). Then  
comes a SPACE (or 20) followed by three ASCII NUL. So the number is  
20,000 hex or 131,072 dec. This leads into the middle of some  
PostScript code. Then follows 7B50 hex (^G^K^E^@) or 31,568 dec. The  
"scrappy" last 327,759 bytes then are a TIFF image of the EPS image...

And 5002.EPSF_Spec describes this header as "DOS EPS Binary File  
Header" – why is it produced on a Mac in a Mac-Roman encoding?
