Christ Church, Oxford, December 31, 1891. One sheet folded to make four-pages, 5 1/2 x 3 1/2 in. (140 x 89 mm). Two-page autograph letter, signed by Lewis Carroll to an unknown recipient ("Lewis Carroll to F.A.S." in pencil in another hand on verso of conjugate leaf): Dear Sir, I am neither the author, nor owner of copy right, of any plays--If you wish to dramatise any book for yourself, you have full right to do so--Also, if you wish to perform, in public, any play, you have full right to do so, so long as you do not charge for admission. But, if you mean to charge for admission, you will need permission from the holder of the copyright of the play, & also a theatrical license for the building to which admission is charged--That I believe to be the state of the law, as regards dramatic performances--Believe me truly yours C.L. Dodgson". Creasing from when folded; old mounting residue at top of final blank page.
