An alphabetically organised collection of postmarks on over seventy entires and covers from 1600s through to line-engraved frankings, varied condition with some marked with the collector's reference codes in pen, yet some scarce strikes in very nice quality, incl. bishop marks, circular undated mileage strikes of Barnsley and Selby, circular dated mileage Scarborough, straight-line mileages for Beverley (1818), Boroughbridge (1807), Bridlington (1809), red Brough (1825), Pocklington (1816), Pontefract (1818), purple Rotherham (1807), Tadcaster (1827), Thirsk (1815) and Whetherby (1819). Other good postmarks are attractive centrally struck Bedale straight-line (1792); red oval 'Paid at...' strikes and red circular 'Paid One Penny' of 1840 (latter with 'N's reversed); circular undated Guisborough in red (1834); an 1852 cover with all blue cds strikes of York, Northallerton, Grosmont and 'Gisboro' - the latter abbreviation stated as apparently unrecorded; 1839 part-cover to Grassington with 'Gomersal Penny Post' Italic straight-line along with red oval 'Paid at Leeds' and manuscript 'Missent to -' beside Carlisle cds; another manuscript 'missent to-' (Bishop Auckland cds) with 'try Auckland' in another hand, along with '1d' and 'Paid at Leeds' on September 1840 letter from Charles Fowler, author of Fowler's Railway Traveller's Guide, to the Bishop Auckland & Weardale Railway requesting data for his coming publication. The greatest range for a single town is on Hull, including 1669 bishop mark cover, another bishop mark with large 'Hull' straight-line (c.1700), scarce double arc '234' type (1826), travelling/temporary arched strike in blue (1840), large blue 'Ship-Letter' strikes and an absolutely superb strike of a spoon duplex tying 1d red stars to cover. Much more here to see, a most interesting specialist's collection.
