112 State St.
ESTATE OF C. H. McCORMICK.
Luxfer Prism Company, The Rookery, Chicago.
In reply to your inquiry, I take pleasure
in stating that your Prisms, placed in the pavement in front of
Mr. Cyrus McCormick's building on State street, have effected a
marvelous change. The basement, formerly so dark as to be of no
value, excepting when lighted artificially, is now as bright as
any first floor on the street. Fine print can be read at the
rear, eighty feet back from the sidewalk.
This daylight result has truly made an
entirely different proposition of this portion of the building,
and I estimate has added five hundred dollars a month to the
renting value of the property.
Yours very truly,
