Depends on the quality. If it is well made, rounded rim, smooth glass then it may be Leerdam from the 1930s - there have been a few experimental pieces made in this crackle technique - Lanooy, I think, and usually unsigned.
However if the surface is rough, the top is cut off and ground down you are looking at a Romanian piece circa 1980. I have one in red which really tears the skin off your fingers.
No it is not classed as stretch glass...
