Overview
The item is explicitly labeled 'Book Mark' on the front, alongside a woven view of St. Paul's Cathedral and the River Thames. The reverse serves as an advertisement for the Northern Assurance Company, which acts as the identifiable issuer for this piece of ephemera.
Story
This bookmark was issued as a promotional item by the Northern Assurance Company of London & Aberdeen circa 1907, capitalizing on the popularity of woven silk novelties during the Edwardian era. While the specific weaver is unconfirmed, items of this quality were predominantly produced in Coventry, England, the historical epicenter of the British silk ribbon weaving industry. The secondary market for Edwardian woven silk ephemera is niche but stable.

Northern Assurance Company
Condition & Value
For woven silk ephemera of this age, value is highly dependent on edge integrity and color preservation. The primary condition factors to evaluate are the presence of fraying at the top and bottom margins, splitting along any horizontal creases, and foxing or staining on the reverse side.
Full Research
Sold comps, value drivers, and venue guidance pulled from recent auction results.
The secondary market for Edwardian woven silk ephemera is niche but stable. Items like this appeal to crossover demographics: collectors of 'Stevengraph-style' woven silks, and collectors of early 20th-century insurance, financial, or London-centric advertising. While inventory moves relatively slowly, highly detailed architectural views perform better than text-only variants. Prices generally remain modest unless the piece is attached to a premier maker or retains its original presentation backing.
▲ Detailed architectural view of St. Paul's Cathedral elevates desirability over text-only variants
▲ Dual-market appeal to both woven silk collectors and insurance/financial ephemera buyers
▲ Printed 1906 financial figures provide a secure, verifiable Edwardian date
▼ Unverified maker — lack of a premier Coventry weaver mark (e. g., T. Stevens) limits the collector ceiling
▼ Condition sensitivity — any unmentioned edge fraying or silk splitting would drop value to the $10-$15 floor
▼ Absence of an original presentation card or tassel limits the 'complete state' premium
Best Venue
List on a broad online marketplace such as eBay or Etsy, as these platforms capture the specific niche collectors looking for this material. Utilize strong keywords including 'Edwardian Woven Silk Bookmark', 'Northern Assurance Company', 'St. Pauls Cathedral', and 'Stevengraph-style'. An optimistic list price of $25 with 'Best Offer' enabled is recommended.
Upside Potential
If a microscopic maker's mark for a premier Coventry weaver (such as Thomas Stevens or W. H. Grant) is discovered folded into the very edge, or if the item is found to be in pristine, unfrayed condition, the value could push toward the $35-$40 range for dedicated silk collectors.
