found this at Stamp Collectors World Net:
Back in 1929 the late Al Burns published these 10 Commandments in Weekly Philatelic Gossip.
Richard Deutsch, who edits the journal of the Garfield Perry stamp club of Cleveland, Ohio, ran across them in 1951.
Feeling that they are just as applicable today as they were in 1929, he printed them in the Garfield Perry Scope with a bit of personal comment.
I am passing this old newspaper clipping on to the members of our community:
1. Thou shalt not at anytime criticize what thy fellow collector collects.
What the other man collects is no concern of yours, be it what it may. If he wants Airport dedications that are supposed to be pure favors, let him. That's his choice and he will stick to it. A lot of confusion and squabbling could be avoided if this principle was followed.
2. Thou shalt be ready at all times to help any collector who seeks aid of thee.
Too many hobbyists have reached the point where knowing practically everything about their branch of Philately, they look with scorn at the novice who is seeking aid. Lend the helping hand and help clear up the beginners trouble
3. Thou shalt study thy stamps, for full enjoyment comes only with knowing them thoroughly.
The man who knows the who, which, and where about each stamp in his collection is the man who can really say he derives pleasure and benefit from it.
4. Thou shalt at every opportunity boost the advantage of stamp collecting. never missing a chance to bring a new collector into the fold.
Many a prospective devotee is lost to philately because some more advanced collectors failed to advertise stamps to the limit. Never miss an opportunity to ad new converts, for more collectors means more publicity, more publicity means more interest, and more interest means a bigger and better hobby.
5. Thou shalt seek the companionship of other collectors for thine own as well as their benefit.
One should not miss the chance to improve himself and his knowledge by refusing to associate with other collectors. Philately is a friendly hobby, drawing people together in the appreciation of a common interest.
6. Thou shalt work with other collectors for the advancement of the hobby.
The chance to work together for the advancement of a cause comes to very few of us in life. As excellent as the stamp game is today there is still much in it that could be improved.
7. Thou shalt at all times do all within thy power to keep the hobby clean and free of anything that may reflect badly on it.
There are many "crooks" and " spongers" in the hobby and it is the duty of every collector to help fight and exterminate them,
8. In thy dealing with other collectors thou shall act so as to be free of all disparagement at all times.
Deal fairly with other collectors, in lending them a helping hand. Give a break to the other fellow. "do unto others as you would others should do unto you.
9. Thy shalt not be ashamed of thy hobby.
10.Thou shalt be ready at any time to ask any questions that may puzzle thee not hiding behind a mask of assumed knowledge.
Don't be afraid to ask questions that are keeping you from a better understanding of the game.
Follow these and you will be a better collector for it.
