If you're a collector fascinated by the Apollo Moon missions, here are a few space memorabilia sales you definitely won't want to miss in the coming weeks.
We recently reported on HA.com's upcoming sale of an Apollo 13 "Flown LM Systems Activation Checklist Book" - also fascinating as the checklist contains dialogue later recreated for a pivotal scene in the 1996 Tom Hanks-starring blockbuster Apollo 13.
That piece is estimated at $25,000-35,000 and is from the personal collection of Mission Commander James Lovell. "It is extraordinary that [this] is not in a museum," we wrote at the time.

Also from Commander Lovell's personal collection is an Apollo 13 flag which was flown in space during the crew's famously unsuccessful mission. It is signed and will auction in HA.com's sale with a crew-signed certificate and an estimate of $4,000-$6,000.
But what if your budget doesn't stretch to $6,000? Well, while Apollo missions 11 and 13 get most attention, the onus falls on collectors to ensure memories of the brave men of the other Apollo missions are preserved.
And you can get some bargains in the process...
Like this set of three autographs signed by the crew of man's second successful Moon mission, Apollo 12 - a mission whose length and scientific accomplishments outdid Neil Armstrong and Buzz Aldrin's achievements during Apollo 11.
We have the three signed photographs for sale priced at just £895 - a very low price compared to Apollo 13 crew group autographs which command an average value of £9,500 on today's markets - up 6.15% in the last 12 months.
Also for sale elsewhere is this space flown flag from man's final Moon mission, Apollo 17.
It measures 4 x 6 inches and is notably mounted on "an unusual" Goddard Space Flight Center presentation certificate. The centre was NASA's first space flight center, established in 1959.
"This flag was carried to the Moon aboard the spacecraft America Apollo XVII, December 7-19, 1972," reads the certificate.
Billed as an attractive piece, this Apollo 17 flag is estimated at $2,500 - 3,500 is currently for sale in an online auction by Ira and Larry Goldberg of Los Angeles, US - a great bargain price considering this item has been flown in space.
Online bids for the Apollo 17 flag close in nine days, on December 3.
