Not available. Most any online source. 68 pages spiral bound. Many have talked of a "reprint" but this apparently is a challenge due to the passing of Mr. Reheis in 2011.
The kids now own the copyright. Someone who knew him could contact the family and see about doing a reprint - in actuality it would probably be best for someone to get permission to finance a set number of copies with a royalty paid to the owners.
They could also gift or sell the rights to someone. I think MARC, MAFCA or the MAFFI would be willing to produce and sell copies.
(2) Where an author is dead, his or her termination interest is owned, and may be exercised, as follows:
(A) The widow or widower owns the author’s entire termination interest unless there are any surviving children or grandchildren of the author, in which case the widow or widower owns one-half of the author’s interest.
(B) The author’s surviving children, and the surviving children of any dead child of the author, own the author’s entire termination interest unless there is a widow or widower, in which case the ownership of one-half of the author’s interest is divided among them.
(C) The rights of the author’s children and grandchildren are in all cases divided among them and exercised on a per stirpes basis according to the number of such author’s children represented; the share of the children of a dead child in a termination interest can be exercised only by the action of a majority of them.
(D) In the event that the author’s widow or widower, children, and grandchildren are not living, the author’s executor, administrator, personal representative, or trustee shall own the author’s entire termination interest.
(3) Termination of the grant may be effected at any time during a period of five years beginning at the end of fifty-six years from the date copyright was originally secured, or beginning on January 1, 1978, whichever is later.
