Somewhat to our surprise, Google does not yield many results for this particular card in mailed condition.  But it’s a good Tuck card and here is the full description:  Oilette card 6261 captioned “FieldCourt Gray’s Inn”, mailed in London in 1927 with stamp and full postmark.  If you are collecting Raphael Tuck cards, this would be a nice addition.  Grade: 1
