Philco Series 9009E, Missing Word Series, The Philco Publishing Co., Holborn Place, London, W.C. Postmarked Redhill, May 22, 1909 and addressed to Mr. M. McAulay, Drumlanrig Flower Gardens, Thornhill, Dumfriesshire, Scotland.
There's a rather cryptic message written on the reverse: "Dear M. - (word scratched out) away at present, but will write when she comes back. She would have written to you long ago, but you did not give her your address. Hope you are getting on well. All much as usual about here. Kind regards from Eleanor".
