A RARE envelope sent to Huddersfield more than a century ago was sold at auction for double its estimate.
An unnamed bidder paid £1,955 at the sale in London.
The 1879 envelope is adorned with a caricature reflecting the vaccination controversy of the times.
It was sent from Dewsbury to an address at St John's Road, Huddersfield.
Auctioneers Spink had estimated it would fetch £800.
But in a flurry of bidding at the London sale it went under the hammer at more than twice the amount.
The envelope came from a collection by American man Louis Grunin.
The collection sold for a total of £335,823.
