Oil on paper, ready to hang.

If you're interested in vintage embroidery, you'll recognise Semco as a long time supplier of craft kits. I think they started in 1915. This ephemera from Jeanette's Work Box (in Melbourne I think) dated from the 1960s and it deserved to come out of someone's files of 'stuff' and tell a story. Edges of canvas painted white. I haven't applied gloss or varnish to the unpainted paper.
