3 large pillows (Maida Vale W9)

These have been stored (in plastic bags) in a loft for decades. They are 30"x20"x10" and covered in a knit fabric, that seems to be wool. Two are cream coloured and one is half cream half grey. One of the cream coloured ones has some grey dust marks in one corner. The covers are stiched (not buttoned or zippered) on. They are possibly pre-WW2.
