"Don't tell my mother I work in advertising, please tell her I play piano in a brothel". During those years the image of such a job was not of hi-profile! Nobody knows the reason why I left my studies in engineering to start firstly with graphic design, art direction and then with marketing, my actual secondary job (now my first job is updating my Exakta pages!). Now (I am 59 years old) I know the reason.
Probably you wish to know why I started collecting Exaktas. I think you can find the answer on my articles about "The tortuous path towards an Exakta collection".
