| Description | 'Dear Sirs,
I shall be glad if you will let me know whether you have a portable screen, with fixtures, on sale at a moderate price. It should be somewhere about 8 ft. [feet] square, suitable for receiving an ordinary three-quarter lantern plate projection. We want a screen that is not too heavy, and readily adjustable.
I am, faithfully yours,
Robt [Robert] Harrison
Assistant Secretary R.S. [Royal Society]'. |
