Antedating of "yellow pages" (1930)

[Sam Clements]

In the telephone sense.

M-W strangely has 1952.
OED has 1956 for the telephone sense, although they have the 1908 Sears
catalogue with an asterisk.

Using Ancestry.com, from the Helena(MT.) Independent, September 30, 1930,
p.5(I think), col. 6-7(An Ad):

     Business houses should make sure they have adequate representation in
the yellow pages, the classified section, which is a complete Buyer' Guide.

I didn't go back any farther on ancestry.  Too tired.  May do more later.
The term was commonly found almost every year from 1952 back to the early
40's.
