CA name board as per ICAI ethics, it's urgent

With regard to the size of the signboard for his office that a member
can put up, it is a matter in which the members should exercise their
own discretion and good taste while keeping in mind the appropriate
visibility and illumination (limited to the sake of visibility). Use of glow
signs or lights on large-sized boards as is used by traders or
shopkeepers would not be proper. A member can have a name board
at the place of his residence with the designation of a Chartered
Accountant, provided it is a name plate or name board of an individual
member and not of the firm.
