Vintage Southwestern Bell black glass trinket tray ashtray

I think it was some sort of promo that was given out to employees at some point? it has '90s or 80s vibes to me.. but I cannot seem to find this one anywhere. it's 6x5". excellent pre-loved condition, no cracks or chips. there's a small bit of scratching on the underside. s1008ccxz110322 2,4
