SPRATTS - High Street, Broadstairs, Kent, CT10 1NQ. - Ghost Signs on Waymarking.com

The large painted words OVAL AND WEETMEET were easily visible on the side of this building, but the top line wasn't so easy. If you look really close when at GZ, the letters TTS are visible on the 'top row'.
A little jiggery pokery on Photoshop provided the clue I needed. The top row would have been SPRATTS.
 

In the 1850's James Spratt, an American electrician, came over to England.  Having seen the chewy gristle meal that London market porters made for their dogs, he realised the commercial potential for canning and baking his own version. In 1861 he patented his dog food, made with wheat meal mixed with rendered meat and vegetable which was then baked. Spratt's became the world's first large scale manufacturer of dog biscuits, and had become a dog food pioneer, with a concept of animal life stages and appropriate foods for each stage.  Spratt's WEETMEET #1 was promoted for puppies, "from the time of weaning, builds up the puppy's frame, muscle and digestive power." Spratt's OVALS, and later BONIO, where soon household names world wide.
