We Do Not Undertake Valuations
Unfortunately we do not undertake valuations or appraisals, so are unable to value your Lowry print.
This is for several reasons, but mainly because of the large numbers of requests we have received over the years via the internet for valuations, and because an accurate valuation can really only be provided on sight of an artwork, which makes it possible to correctly identify and assess the item, its condition, quality, and other important factors.
As a general rule, the most desirable Lowry prints are those which he has personally signed. They normally have a pencil signature (usually in the margin outside the actual image area), as well as the printed signature which forms part of the image.
Prints which only have a printed signature within the image are not classed as signed prints, but prints issued in numbered limited editions, especially those published during Lowry's lifetime, do possess a reasonable value.
Lowry was arguably the most famous British artist of the 20th Century, so unsigned prints of his work were produced in huge numbers, in open editions. Unfortunately these reproductions only have value as decorative items - in other words they have little or no value.
If you do require a valuation of your Lowry print, you could approach a good local auction house, or any art dealer who offers valuations for their advice, or search the internet for one of the online art valuation/art appraisal services that now operate on the Net.
Hopefully this information has been of some assistance to you.
