Hi again,
now I have checked and found Alan Thornton's article about two J-Glass brochures of 1978 and 1979 he has found,
Alan reports about it in the Paperweight Collectors Circle Newsletter No 113 from November 2013, and on page 7
you find the 1978 leaflet- weight number 6 bottom left is a "flower on a millefiori garland(blue)"- it has got a light blue ground,
but has the same layout as your- the signature should be placed at the tip of the flower's stem- although, I have seen examples
where the signature has "sunken" or toggled,
hope this helps, Kind regards e.
