Dancer is not well known for his microscopic slide preparations, with the exception of microphotographs, of course. So it is rare to find slides with his labels. The few I have found are a white label similar to the better known yellow microphotograph label, with the initials J.B.D. In the bottom right corner and a slide number in the left bottom corner.
Like many other opticians of his day, Dancer sold slides by other preparers and over labelled them with the gold on black “J.B.DANCER, MANCHESTER” label.

Some “other preparers” slides retailed by dancer, including the very best preparations of the day by top preparers such as Topping.
