Below is a full listing of Stevens silks in each category, together with scanned images, which themselves are from a wide variety of sources and as such vary in quality.
The information contained in these listings was initially derived from Geoffrey Godden's book Stevengraphs and other Victorian silk pictures. The late John High, a then member of the Stevengraph Collectors Association, very kindly gave me access to his un-published lists which greatly extended our records, particular of the Alpha Series silk postcards which had not been documented before.
Thomas Stevens invented the title "STEVENGRAPH", and the first recorded use of this title was in 1876 on the stiff backing paper used to support his woven bookmarks in the post. Stevens also later named his factory in Coventry, "Stevengraph Works" and this again first appears on the bookmark stiff backing papers of 1878 - 1880.
Today it is assumed the Stevengraph title applies only to his woven silk pictures. As these however did not appear until May 1879, it is evident Stevens intended the title to include his silk bookmarks and portraits, as well as his pictures, and later, his postcards too.
