Thanks

I am looking for advice on how/where to sell a large, vintage space-stamp collection. It was my father's, the fruit of over 20 years of obsessive collecting, and contains thousands of stamps, first-date covers (one signed by Werner von Braun), also some astronaut correspondence, medallions, etc. It is also carefully annotated with text on numerous events, milestones, etc. It covers much more than just manned space flight, and is really comprehensive (he was something of a space historian, as well as a rocket-fuel chemist). As a non-philatelist, alas, I don't know where to begin. Stamp shows? On-line venues? Any advice would be appreciated!

I hope you are well Joe and Happy New Year from Scotland.

I collect stamps with Albert Einstein on them. A couple years back I bought 23 Apollo 15 tracking station covers, most signed by the tracking station director. All are United States or U.S. terratories stations, and each has an Einstein 8 cent Prominant Americans stamp on it. I was thinking about filling out the small collection. But, I don't know what that would entail - could I get more with the Einstein stamp? How many covers would be in a full collection? What would the cost be? If, I go forward with this, could you help me? Or, if the project would be too big, would you e interested in buying these covers?
