Thanks to the awesome book-finding abilities of Brian from Porcupine Books WINOLJ I have just ordered a bound volume of Harmsworth's London Magazine containing the original illustrated version of Kipling's As Easy as A.B.C.. It was serialised in March-April 1912, and is one of the stories that the first Forgotten Futures release was based on. It's coming from Canada so will take a while, but if all goes well I hope to have the illos on line in a month or so, and really high resolution scans on the next Forgotten Futures CD-ROM. Someone recently listed the first of the two issues on ebay at a ridiculously high price, £400, which is what prompted me to start asking about them - Brian found the bound volume (6 issues) in less than a day, and at less than a tenth the price including transatlantic postage!
Incidentally, the ebay listing includes a couple of pictures showing illos - I won't have the cover, they weren't included in the bound volumes, but the rest of it looks very cool:
