Here we have Ray Milland himself. The back of the card tells us that he was "..born in Neath, Glamorgan, on January 3rd 1905". It also adds that he was "..educated at King`s College Cardiff". Then it says that his "real name is Jack Millane". Have never heard this one before - does it appear on any other cards?
Now the text also includes a mention that "A British Film Star gave him his film chance" - this is curious, as it is usually said that his big leap was caused by Estelle Brody, who he befriended and she gave him a little part in her next movie, "The Plaything". Problem is that Estelle Brody was an American, born in New York in 1900 and of half Russian parentage. She did come to England in the 1920s, where she was a dancer on the West End Stage, and was spotted by a film director who liked the look of her and put her in his next movie. She was popular with the audiences as well. Now this is where the confusion seems to come in as at that time, much as today, the emphasis was on home grown films and stars, so her American roots were covered up under the guise that she was Canadian. When she started playing in more British pictures this was further fudged over by her adopting a more British accent and not declaring any place of birth.
This card measures 67 x 36 m/m and is a black and white photo. Note the "PARAMOUNT" within the photo, that is the Studio for whom he was contracted and who supplied the photo.
The back seems to be for R J Lea but it actually has what is known as "Successors" wording, and this refers to the fact that R. J. Lea had just gone into voluntary liquidation - this was reported in The London Cigarette Card Company`s "Cigarette Card News" July 1938 magazine, vol.5 no.57
