October 4, 1928 Mr. George D. Sack 350 E. 57th St. New York, N.Y. Dear Mr. and Mrs. Sack: I suppose you are back in New York from the farm and I hope Mrs. Sack’s mother has recovered her health and that you folks are happy in being back in the big city. You will be surprised when I tell you I am having a little exhibition at the Grand Central Galleries of bronzes and a few paint- ings in the little inner gallery, the small room where your paintings were last year. This exhibition is to open October 24th for a period of two weeks. I expect to get into New York the evening of the 23rd and of course look forward to seeing you people as much as possible during my stay. I am going to make you very happy and curious because I am bringing two little originalsmodels [sic] by Charlie for you to see. I was able to get them in Montana this summer, one is a saddle horse the other a pack horse with all their equipment on them but no rider. You see I didn’t forget to look out for your collection. My kindest regards to you all. Sincerely, MGS [Transcript by Lauren B. Gerfen, 2012-09-13]
