The "bomber" caricature displayed on my home page (and used on much of my personal correspondence) is a registered trademark with all rights reserved.  The emblem was first used by the author (then a relatively novice bomb technician) in interstate commerce as an identifying service (trade) mark in December 1971.   The emblem quickly became an internationally recognized symbol of law enforcement and military bomb / EOD (explosive ordnance disposal) technicians.  It was ultimately registered as a service (trade) mark in 1979 in order to protect the symbol, and to make its use exclusive for law enforcement, military, and other bomb technicians and investigators.

The rights to the caricature mark were subsequently assigned to the International Association of Bomb Technicians and Investigators (IABTI).  All rights pertaining to the use of said mark are reserved by the IABTI.  The caricature has been called the Mad Bomber or the Little Bomber by some bomb technicians, while others (especially Canadian and British technicians) have referred to it as Guy Fawkes.¹ 

I have always thought of the character as “The Master Blaster”, an individual with a rather unique (and perhaps explosive) personality.  On occasion (and depending upon my mood at the moment), I have also described him as an “Amenable Anarchist”, a very experienced persona, secure in the knowledge that "there are very few personal problems that could not be solved by a suitable application of high explosives . . . judiciously applied".   

Following my retirement from the law enforcement field, and after a very busy and active career as the Senior Bomb (EOD) Technician with a large metropolitan law enforcement agency, (and increasingly as age has progressed), I perceive that the character has deservedly assimilated into the curmudgeonly and perhaps rather grumpy role as “Ye Olde Master Blaster”.  

Additional insight (if really wanted) into the complete history of the "bomber" emblem may be found by clicking on the bomb.   

¹   Fawkes, 1570-1606, was an English conspirator executed for the attempted assassination of King James I and the assembled parliament in an incident that later was to be referred to as the "Gunpowder Plot".  This plot was in retaliation for increasing repression of Roman Catholics in England.  Guy Fawkes Day is commemorated on November 5 in the United Kingdom with many bonfires, the burning of effigies, and various other celebrations.  It is also celebrated on the same date in Canada where it is known as Bonfire or "Bombfire" Night.  

Fawkes was hanged, cut down while still alive, drawn and quartered (four horses pulling the body in four separate directions), and had his bowels and vital organs torn out and burned before his dying eyes.  Where were the opponents of capitol punishment in those days?
