Vintage French 100% cotton flat sheet w matching Euro Sham

Two pieces. The flat sheet is adorable with a 3” ruffle across the top. The Euro (square) sham has a 2.5” flange on all sides. Both have an abstract pattern of pink, blue, and yellow on a white background; with the pillowcase pattern having larger shapes. The brand name (Yves Delorme) is known and respected, but the label here is unreadable; was costly when I purchased it in 1990. Used for awhile, then stored. Flat sheet = 86” x 104” includes the 3” ruffle (comparable to our “Full/Queen” size) Euro Pillowcase Sham, flat = 29” x 27.5” – includes the flanges
