Here it is:
Adrian J. Desmond: The Hot-Blooded Dinosaurs. A Revolution in Palaeontology,
Blond & Briggs 1975
footnote 32 to chapter 6:
"Ostrom, J. H., >>Reply to >Dinosaurs as Reptiles<<<, _Evolution_ (1974),
28, pp. 491 -- 493. _Compsognathus_, also found in the Solnhofen sediments,
was small itself, though bigger than _Archaeopteryx_. It is imaginable that
this coelurosaur bore feathers. According to Ostrom (pers. comm. 4 March
1974) the slab that contains _Compsognathus_ has been polished smooth around
the fossil, by which action eventually present faint feather impressions
would have been destroyed. _Compsognathus_ was discovered _before_ the first
(the London) specimen of _Archaeopteryx_, so that at the time of its
discovery nobody had looked for eventual plumage. In the last three
[remember, 1975] _Archaeopteryx_ specimens the feather impressions are so
weak that the fossils were at first not recognized as Urvogel remains.

Entirely possible, no one says any impressions were present around
_Compsognathus_ before polishing. One or two new small theropods have been
found there in the last few years, let's have a close look at them when they
are :.-( published...
Oh, it's not sandstone, it is plated limestone which looks a lot
like shale (apart from color).
