Robert Heinlein classic books (Western Dearborn)

I have The Notebook of Lazarus Long Illuminated by DF Vassallo out in 1978.
I have four vintage paperback books by Heinlein in good condition and lovely cover artwork. To buy them online would cost at least $50. Have Space Suit- Will Travel. Rocket Ship Galileo. Red Planet. All published by Ace Books. The Day After Tomorrow is published by Signet.
