The first edition BOOK OF MORMON was printed in 1830. It is interesting to note that after 1830, for the next 58 years, all subsequent editions of the Book of Mormon would be printed in a smaller size and font. I recently acquired Helen Mar Kimball's 1841 copy of the Book of Mormon--which was given to her when she was thirteen years old by "uncle" Brigham Young. Helen is the daughter of Mormon apostle Heber C. Kimball.
In her journal she made reference to the smaller-sized print, "There is but one fault I find with it--the print is so fine that many times I have been forced to stop reading it; and this, I believe, prevents many from reading it who otherwise would, as some who are not of our faith but are friendly to this people, have mentioned this to me, and said it was the only reason why they did not read it. This I think is a great pity.".
In the photograph I show several editions, side by side, with the first edition Book of Mormon on the left, and the 1888 pulpit edition on the right. From left to right, these copies of the Book of Mormon were printed in 1830, 1840, 1841, 1852, 1885 and 1888. The photo below is from Helen Mar Kimball's own Book of Mormon.
