Looks like a mould blown cordial decanter to me with a pressed glass stopper, not usually ground in. These were made in bottle works, pre Great War in Germany / Bohemia, afterwards possibly also in Britain. Many of these had designs registered by factors. Freebies with cordial concentrate, possibly at Christmas time? If you keep to examples with Reg. Nos., you can date them.
