Austrian label under AGS-Musikverlag and Belvedere Musik Edition International, presumably founded by Alfred G. Schittler.
The "Garden of Melodies" LP is not branded with "A.G.S." on the sleeve (labels unknown), but has a similar design and composer, and seems to belong here. I think it might be the AS 102 release.
