Sidney Neighbour info plz?

Question

I have recently purchased 4 original works of Sidney Neighbour. They are in good condition, signed etc. They are sketchs of townhouses in sydney Australia, named propertys, brown paper backing etc.Who was Sidney Neighbour, does anyone know of a site to find out who he was and what his works are worth? Do i hold onto them?

I've never heard of him and Googling doesn't seem to help.
