Perfect heavy glass ashtray for the Matson lines ... these would not roll around too much during high seas. The BIG Matson white hulled passenger liners were popular in the late 20's through the 60's. This is probably early 60's mentions 4 ships Lurline, Mariposa, Matsonia and Monterey. Today, Matson lines concentrates on just container cargos and has no passenger operations. Mint: no chips or cracks!
