Please let me know if you would consider this 18 1/2 X 13" toleware tray mid-century modern or not--and would you consider the leaves typical MCM colors?  I am unable to clearly read the signature at bottom--maybe Buchley; have you heard of that artist before?  On the back is: HandPainted for Pilgrim for ZCMI Salt Lake City, Utah or USA.  TYIA, B.L.
