I just acquired these two items.

The blue one is 16″ across, the mark on the back is three letters in a circle. I cannot make out the first letter but the last two are M B. It’s also faintly marked Made in the USA. Does anyone have any thoughts to whose’s mark that is?

I believe the second one is Peking Glass. Does anyone have any information to share on this bowl? It’s about 14″ across and 2″ deep.

TIA
Frank
