Note the left Wrist Garter. Alice Chaucer was appointed Lady of the Garter in 1432 by Henry VI King England II King France 1421-1471 (since Henry was eleven years old at the time the appointment is likely to be by one of his uncles: Regent John Lancaster 1st Duke Bedford 1389-1435 or Protector Humphrey Lancaster 1st Duke Gloucester 1390-1447.
The effigy was, apparently, viewed to determine how a lady should wear the garter at the re-commencement of Lady of the Garter appointments in 1901 after a gap of several hundred years.
A particularly fine example of the Cadaver underneath the chest on which Alice's effigy lies. Full-length in a shroud.
