"John Wallis, with his sons John Wallis Jr. and Edward Wallis, was the most prolific publisher of board games of the late 18th and early 19th centuries.
The company occupied a number of sites in London, including:
* 16 Ludgate Street (under the name "Map Warehouse") from 1775.
* 13 Warwick Square (under the name "Instructive Toy Warehouse") from 1805.
* 42 Skinner Street, Snow Hill. (this address was mainly used by Edward Wallis when working alone or when working with his father, in those cases publishing as "Wallis and Son" or "John & Edward Wallis")
* 188 The Strand (this address being used solely by John Wallis Jnr)"
The George Glazer Gallery says: "Edward succeeded his father and published under his own name until about 1847, at which time the Wallis stock was taken over by J. Passmore", and lists the following references:
