Making old dry wooden dollhouse furniture look even better!

I just got a group of the FORBES Blonde 3/4" large wood items in from CANADA and they are so so dry.....some pieces the glue gave way so I have fixed everything..no breaks just separations...but I was wondering what the best oil or ? was to put on them??? It is a lovely lot of tons and I would like to make them look better before photographing and selling.

Ideas would be appreciated!

I will post photos of before and after!! I hope!
