I don't jump on many palettes these days, as I am quite fussy about the ones I like--so many out there that look as if painted up to look as if they were actually used. But this is a nice old real one, probably tucked inside a painter's box to be used en plein air, with the colors on it just right for capturing a landscapes. Some paint and what I take for oil stain on the reverse side too. Lovely.
10" x 7", very nice presumed antique condition, late 19th/early 20th c. I would think. No splits or losses, very warm patina.
