mid-century vintage ivory white McCoy pottery planter pot, MCP mark

Vintage USA pottery planter pot in an ivory white color - I believe this has the MCP (McCoy pottery) mark on the bottom, but I can't find this one in my books.

It measures about 5" across the rim of the pot, stands 4" tall.

It's been used, shows a little wear and crazing with slight discoloration. Also a glaze chip to the rim (see photos).
