A W Nicholas
Although only one postcard of Brislington is currently known from this publisher, others depict locations nearby in Knowle, Bristol. All postcards cite A W Nicholas' address as Livingstone, Wells Road, Bristol. Although Livingstone has yet to be identified, it may be more than coincidence that the 1901 census shows Alfred William Nicholas living with his wife and children just 100m from the Wells Road in Merfield Road, Knowle (the 1911 census shows this family had moved to live at Bristol Hill, Brislington).

Some notes
Although more information is needed to be on statistically firm ground, first indications suggest the above postcard by Nicholas predates the version published by James Baker & Son (Avonvale Series), but only by a year or so.
