I found this in the 'Bognor Regis Observer' dated 12th June 1929:
“In addition to his wireless activities, Leonard Henry also records for the H.M.V. Gramophone Company, and in conjunction with the well-known firm of Eroica, London Road, Bognor, a special competition will be held during the week, particulars of which can be obtained from Mr. Jack Allen, manager of Olympian Gardens, and also from Eroica. The prize will be a portable H.M.V. gramophone. On Friday afternoon Leonard Henry will be in attendance at Eroica's music salon in London Road between the hours of 3 and 4.30 p.m. to autograph his own records.”
