ANTIQUE RARE MUG MADE by ROYAL RIDGWAYS for POULTRY CROSS SALISBURY CATHEDRAL

This antique ROYAL RIDGWAYS rust brown colour item dating 1920's has a silver tone overlay on rim & handle, and adorned with a SALISBURY CATHEDRAL view. The mug has been standing in a glass fronted display and is in excellent and clean condition, there are no signs of damage anywhere, no nicks, chips or cracks, paintwork bright and clear. Please note! Shows natural crazing with age. Would be an awesome collectible regardless. Colour may vary slightly from the photos due to lighting conditions!

I have taken as many photos as possible and you can get a right idea about the item and condition.
