What to do...

Somewhere around 1911, Mardi (Mona) Green, mother of Neil and Betty Roff, and her family, embarked on a grand tour of Europe. Mardi collected postcards on the journey and, when she returned, put them in an album.
Here's the route she took: Sydney, Tasmaina, Melbourne, Adelaide, Perth, Sri Lanka (Columbo), Suez Canal, Port Said, Italy, Gibralta, Paris, England, Scotland, Ireland, Isle of Man (she beat me to it!), England again, Belguim, Paris again, Holand and then back to Sydney.
There are around 720 postcards in the album, all from the 1911 period. The album itself is falling apart from age and some water damage but most of the postcards are in good condition.
Most of the postcards have no writing on them but some do.
Here are the issues:
1. Some people collect postcards and postcards have a small financial value.
2. If you want to see what London looked like in 1911, you can get images on google.
3. Does keeping or restoring this album have any value in terms of family history.
I think Mardi also had a diary of the trip but I have a vague memory of Aunty Betty telling me it was just a list of who they dined with on the ship and was very short on social analysis. Do the Seages know anything more on this?
Here are some possibilities regarding the album's future:
1. Someone in the family takes it on as a restoration project.
2. I sell it on eBay to postcard collectors. (I've done a little research on this. The collection might fetch somewhere between two and three hundred dollars. The original joke was I'd give this money to charities involved in detention centres as Mardi was a great supporter of multiculturalism but only Uncle Ken and Aunty Betty would get the joke - Mardi, typical of her generation, was suspicious of non-Anglo Saxons. Our ancestoral home, Carrington Hall, was split up into units and Mardi was shocked to find she ended up living with middle-eastern neighbours.)
I'm inclined toward option two as whatever money is raised will go to what I'm sure we all agree is a good cause. I will defer immediately to anyone interested in option one, of course. When you look at the collection, you can imagine Mardi "doing Europe" and it must have been an amazing adventure in the early years of the 1900s.
The pictures attached are just three from the collection. There's the Otway, the liner on which the Green's travelled; there's a postcard from Tasmaina and there's a hand-signed postcard from Frank Richardson who was a women's rights campaigner in England in 1911. Frank has defeated Google in that I can't find any trace of him but he clearly thought that dressing as a woman would support the cause. The Mardi collection has two signed postcards of him indicating she directly engaged with him. Imagine that - Mona Roff at the forefront of women's liberation.
Okay, what should I do with the album? 
PS: Can't upload the postcards - will sort out how to do it shortly.
