And pale pastel colours (mostly). Definitely a fake mark, simply on the grounds that this is absolutely not Vasart glass.
Several different folk actually made the Vasart mark at the time though they tried to write it in similar ways, mostly. The base of the V tends to be U-shaped, there are little curls on it's ends. It was acid etched, often with the acid being painted on using a thick-ish appliacator. Not all neat and tidy, dremmelled like this!
