[Matilda Anne Mackarness, children's writer.] Autograph Letter Signed ('Matilda Planché') to 'Mr Helmore' [the choirmaster Thomas Helmore?], regarding the reluctance of W. N. Wright to publish her 'A Trap to catch a Sunbeam' in cheap form.

3pp., 12mo. Bifolium. In good condition, on lightly-aged paper, with traces of mount adhering to the blank reverse of the second leaf. In reply to his letter, she refers Helmore to 'Mr Wright', who has 'frequently since the Publication of the "Sunbeam" [in 1849] been appealed to to bring it out in a cheap form - but he has no speculating propensities - and as he is perfectly satisfied with the sale of twenty thousand at a shilling - he is not inclined to try it in a cheaper form'. She has 'nothing to do with it - further than receiving a certain sum as each edition is sold out'. She wishes Helmore to know 'how much I estimate your opinion of the little Book', and hopes he 'will do me the favour to accept the few copies I send with this, to distribute amongst your favourite "Davids"'.
