From "national lithographer" vol 28 an ad showing the maximum stone size of the Hoe number 5 and 3 lithographic presses.
From "aluminum world" volumes 4-6 --vol 6 number 3 December 1899. A brief mention of a two color litho press using aluminum plates being installed at ALC. The first mention I've seen of ALC actually having a two color press, which I've suspected they might have had and used for some of the card issues.
So there were a lot of big presses out there.
