Original source of Tuck anecdote?

I’m currently doing some Tuck research as a personal project, and I am trying to find the original source of a regularly quoted anecdote. Does anyone know where the following anecdote was originally published or originally comes from? It goes:

"The president of the Royal Academy [of Arts, in London] … expressed his opinion concerning Tuck’s influence on art. He said, “Mr Tuck’s graphic productions were likely more effective than all of the art galleries in the world.”

Any help would be gratefully appreciated.

I found it (and more!). No replies necessary
