A lot of four Berkeley Books paperbacks by Robert A. Heinlein:
PODKAYNE OF MARS. Berkeley Books, 1970. First printing. VG, tipped, spine creased.
THE MOON IS A HARSH MISTRESS. Berkeley Books, 4th printing, 1969. VG+, lightly tipped, spine lightly creased, top right corner creased.

FARNHAM'S FREEHOLD. Berkeley Books,9th ptg. VG: tight & untipped, spine uncreased; two diagonal cover creases on front cover.
I have other Heinlein paperbacks for bid/sale -- more early paperbacks and some lots of later paperbacks. Always happy to combine postage.
