Thank you for your replies.I couldn't access the Farthest Reaches website with my provider (I'm in France) so I thought it was no longer in business. Using a VPN located in Germany it worked...
This website is still a goldmine but I forgot that all the items are signed.
I'm not fan of auctions even if it is the norm for this type of items.
I have a very small collection and not a high budget. I found back that apollomissionphoto was selling NASA reissue of Apollo mission for a very reasonable price (with NASA logo, number, Lyndon B Johnson and text on the back.
I like press release photo too (with the purple text on the back). Ideally photo of the astronauts on the moon.
