Yes, in the right places. Like the Österreichisches Staatsarchiv, for example. You might even find pictures of Wolfy and Billy, like this one.   Billy is in the center foreground with his back to us, as it often was to Wolfy, who is seated at the head of the table, fourth from the left.

The picture, by the way, is of a certain Biergarten in Vienna called, for some reason, "Der Gai Vacquero".
