Kudos to Steve - that is correct! Once, on a trip to Boston, Mary attended a seance using the name "Mrs. Tundall" to avoid recognition. Abraham "appeared" before her during the seance. She then visited William Mumler's studio. Mumler was a spirit photographer. He produced a photograph of Mary with Abraham superimposed in the background with his hands on her shoulders. This photograph gave Mary a pleasant feeling that Abraham was hovering over her.
