Looked thru my issues of TGS and I only have 1983 to present and did not come across Gedeon Aucoin in the indexes.

They have the issues v. 1 - 1982 - 3 bound issues for sale $25.00
but there is no guarantee your Gedeon Aucoin is listed in these 3 issues
it all depends on the page numbers usually each issue contains 25-40+ pages

try writing to TGS
PO BOX 20295 HOUMA, LA 70360
And ask if they will search in the 1982 for Gedeon Germain Aucoin
