I've designed Logos since 1974, beginning with my first corporation "Beta Plastics, Inc", Then my next "Teckna Marketing Corporation", until finally the last of my own as Teckna Design/Builders.
I done advertising and corporate work, for major clients in the mid 1970's to 1980's in all types of media.
Since I began blogging in 2005, I have changed logos & avatars a few times. It has been an evolution of my own basic appearence, and yes, I have obviously aged!
