Fake Or Real Deal? Weird Cover

So what I learned here is look at the stamps that were used, they are off centre, the stamps were left over stamps.
The name of the sender is no guarantee, even if he is a famous philatelist.

Keep your eyes open when you buy something and if you are in love with an envelope that you want to buy, ask an other philatelist what she or he thinks about the envelope.

Reminds me of a buy that I made this year from a well known dealer, I bought 3 albums with Netherlands, all stamps were spacefillers, these were no collections collected by philatelists, it was his spare stamps, left overs.
Its no coincedence that some same stamps were damaged in all three albums. That was on purpose!
So I lost some money and he lost a relation in the first days I met him, a logo of an organisation is no guarantee.
So keep Always your eyes open!

I was the one who let this happen, the 3 albums was peanuts, I was at his store to investigate his behavior.
I was looking for a new business relation that I can trust on his word, I will never buy something again from him, I think in the long term. He wanted to make a profit in the first meeting.

O.K. Thanks for the information peoples. I did not know that this was from a famous philatelist until I got here and posted it. Thanks everyone for your help.

I talked with The ebay Seller today. It was addressed to the mayor of what ever town that was in California.

It was to help him get started in his stamp collecting. I think he said 1933. Thanks

Update here is the back of the cover withe the dates. Thanks

Just for the record, not all covers with stamps that are from different periods are "philatelic covers". My local stamp shop used to sell mixed packets of unused stamps. The general public would buy these and use them to pay bills and such. As a stamp collector, I acquire lots of unused stamps that I use to mail letters. These are not designed to be collectible covers, I'm just using old postage.

Often my friends save envelopes form me because they find the assorted stamp interesting. Some people have an arrangement from billing centers to get their incoming envelopes, mine included. If it looks odd, they may save it. It may end up in a stamp collectors hands decades from not.

Ok,Thanks for the information. his site is very helpful.
The letter is also unopened. Should I open it and see whats inside?
Yes this is the guy that wrote the book in this post also.
So is it worthless? Should I toss it? Thanks

Regardless of it's origin your cover is "Interesting" and has eye appeal so I definitely wouldn't toss it. It probably is a cover sent by a stamp dealer to a customer and he used an assortment of stamps. Did he do this because he had the stamps laying around, or to please the customer or to create a collectible cover? Who knows, but the result is a cover that 84 years later is cause for a nice discussion.
I like it!

It is from R.D. Macguffin he wrote a book on philatelist.
