I do know that some dealers have a small section of boats or ships, but the all-inclusive section unless fairly small is like a sinking ship, totally unmanageable. There are canoes, rowboats, battle ships, inland steamers, ferries, paddle steamers, submarines, air craft carriers, sail boats, steamships, ocean liners and a flotilla of other types of water transportation including rafts. The more specific you are in your request, the easier it is for you to access what you are looking for. If you are looking for menus from a Cunnard line, tell the dealer that is what you are looking for. If in fact you truly want menus, inclusive of restaurants and railroads, then that is a different story.
Dealers usually know their stock.
Don t waste your time aimlessly looking about. Every paper dealer files and catalogues differently. Just requesting boats or ships won t do. Beside the large dinner menus which were changed every day on the luxury liners, there were smaller menus attached via perforation to the bottom of postcards. The idea being you tore it off, circled the items you selected to dine upon, and kept the top part of the card which you could then mail.
