Thank you for the assessment, I only collect them in memory of my beloved brother who was an avid collector as a boy in the fifties before I was born, he died as a result of injuries sustained in Vietnam, so it’s for him I continue the tradition. However, I am awaiting a bilateral lung transplant so paying too much is my only concern. I love them, they are like little pieces of art, the following photos, albeit still not great are of alleged Christensens I have purchased. Thank you for your help, sir, it is most appreciated.
