HI Paul,
I had a bas relief card Zena Dare and it sold very well despite her nose being rubbed off!
I have found this little bit of info for you:
Alliance Ltd 1902. Publishers 115 Newgate Street London EC. A firm formed to produce bas-relief cards, a type invented by Freeman Augustus Taber of San Francisco. (Taber Bas- Relief Photographic Co) The Alliance output included, Real Photos of Actors, actreeses, horses, Jockeys and views of the river Thames.
The firm was closley realted with A G Scopes & Co which shared the patent for the procrss registered in 1908.
"P Scopes & Co. Ltd c 1908, Publisher, 1 Cotton St, Barbican, London, and after c.1917 at 4 Lauderdale Buildings London EC. Trademark "ALLIANCE".
The firm shares a patent with Alliance Ltd., for bas-relief work. During WWI they also used the title "Britannic". The output consisted mainly of portraits, patriotic cards with flags and a military portrait, photographs of animals and greetings cards".
also from "Picture postcards and their publishers":
A number of bas relief cards carry the name of Scopes & company, but the same type of card appears with several other names, including Tabre, Alliance, Beagles and Rapid Photo Company, and many collectors have been unable to sort out the various patent numbers cited on the cards. The basic patent itself is described fully in the article from the Taber Bas Relief Photo Co, but need to be breifly outlined here to explain the part played by Scopes & company.
Freeman Augustus Taber registered his original patents in 1895 and 1896 and these, two years appear after the patent numbers 21422 and 17225 on the back of many bas relief cards. Alliance Ltd took over the patent in this country (UK) and at times allowed other companies to issue bas relief cards under licence.
However in 1908 an updated patent was applied for by Alfred Scopes and Alliance Ltd jointly and was registered under the number 4253/08 and this explains the different number shown on scopes cards, despite the fact that it is basically the same process.
During the first world war the firm took over H W Lightfoot & Co of 9 Long Lane London who published the Britannic series of postcards. They continued the series name and the same cards can be found nbearing either the name of lightfoot or scopes. These cards were of a patriotic nature with the addition of an inset view of a popular personality and sometimes with the addition of a greeting.
Hope that helps!
