The stitching in this beautiful sampler with the sacred hearts includes the name Malvina Roisset and the date 1891. I think Marie Louise Malvina Roisset, who would have been 10 years old in 1891, could very well be the stitcher.
Pattern is stitched on 36ct linen using Caron Impressions. Stitch count is 166 x 172. Finished size is 10" x 10".
