Bruce....I would tell you to go on to the other 600+ Newsboy cabinets, but I don't want any competition! As to Mark......there are really subtle differences with a lot of the Newsboys.....cropping, titles etched onto the negatives versus not, mount differences, etc. While they are attributed to mid 1890's, I wouldnt be surprised it they were used for a number of years for the product. I have a couple hundred of the non-baseball ones and concentrate mainly on non-actress ones and there are definitely variation in those. Battleships, Bicycle Riders, NYC Scenes, Washington DC scenes, etc.
Great stuff Bruce.........not sure if you've seen the Newsboy site that Michael Reeve in England did but it's located at:
