Pictured below is a page from one of their sketch books.
On this page there is a sketch of a lady figural flower frog.
I quote from this website:
'Gradenberger an Austrian glass mould maker commenced business in 1949.
It is said to be still in business making moulds for the glass making industry.
However it now goes by the name of OMCO.'
This information has been brought to my attention by a collector from Wales in the UK.
It was brought to my attention by a collector from West Yorkshire in the UK.
It has 10 flower arranging holes.
Seen in pink with a frosted finish.
Other colours likely are crystal, amber, green and blue.
It is Extremely Rare
The Maker and Country of Origin is unknown at this point in time.
A glass catalogue needs to be seen to confirm the Maker and Country of Origin. Should you have or know of one please contact me.
