Definitely not Monart - it's surprising how much glass is still labelled as Monart by auction houses when it isn't - sometimes it may be Vasart, other times it is no relation to Monart. I've given up emailing them now as they never seem to correct the listings.
If in any doubt always ask for a base shot and check the shape with the Monart catalogue (but some of the Czech ones are the same or very similar shapes) - I think we've all been caught out at one time or another - it's all part of the learning curve.
