Luxfer Prism Co., Chicago.
Gentlemen:
When I gave you the order to equip my store
with your product, I expected good results; now that the work is in
place I can hardly find words to express my appreciation of it. In
the sale of gems perfect light is of the highest importance. The
daylight brought in and distributed by your Prisms gives us ideal
conditions not to be had by any other means so far as I know. I
regard them now as a necessity.
Yours very truly,
