24" x 14" and 4" thick. (I have two if you would like to purchase two). I have had it for over 25 years and it was already old when I acquired it. I lovingly washed the casing by hand and sun dried it. From an always pet free and smoke free home. The insides are good also. Has been mostly in dry storage so still plump! The bird and flowers details are a bit 'raised (stand out). There is a working metal (not plastic) zipper on the case (which usually indicates it is antique). There is batting on the inner part. Faded look. I also have a few other vintage/antique unusual pillows for sale. Please note they are faded as they have been washed many times over all these decades!
