Girasol Collectibles (aka Adventure House) has been the most dogged of them all. They have reissued the novels as both a series of single pulp novel facsimile editions, as well as re-typeset stories in "pulp double novel" trade paperbacks. Both series use the original pulp magazine cover artwork for their books. Girasol published the first 23 issues of the original pulp series as "facsimile" editions. They also published 25 of their "double-novel format" issues, which totalled 50 novels reprinted in all (#'s 1, 3, 9, 10, 11, 13, 14, 19, 20, 22, 25, 27, 28, 29, 32, 34, 35, 42, 43, 49, 51, 53, 54, 55, 57, 59, 64, 66, 70, 71, 72, 77, 82, 83, 86, 87, 91, 95, 98, 100, 101, 102, 103, 104, 105, 107, 108, 110, 112 and 114.)
