Sir: 1 April 1996 marks the start of the Welsh Year of the Logo. From Monday, 37 district councils, eight county councils, nine district health authorities, eight fire brigades and their logos all bit the dust. In their place we have 22 unitary authorities, five district health authorities and four fire brigades, all with new logos. Where were the share tipsters' calls to invest in logo designers, printers, sign writers, crest designers? It must be Wales's boom industry.
