17th & 18th century ships on framed seals & maximaphily!

As a former collector of maximum cards, I immediately wonder: “Which 84 etchings by Gerrit Groenewegen (1754 – 1926) did graphic designer Bart de Haas use to execute this issue of ten 17th and 18th-century merchant and State fleet ships in this way?” For this, see the article 'Scheepvaart in de 17e en 18e eeuw' by Randy Koo (April 7, 2025), designed in an attractive manner. End of maximaphilia! After a search, by looking and comparing on Google, I finally found all the original ship images. However, no picture postcards of these exist to elevate them to maximum cards with a stamp and postmark. Cancellation of the cards is no longer possible. The PostNL cancellation service has been discontinued as of January 2025, with which maximumphilia has come to an end as a philatelic branch! Nevertheless, I do not want to withhold the appeal of the maximaphily from you. Here are images from the Merchant Navy stamp sheet: * 1 through 5 are taken from the Merchant Navy stamp sheet with brief background information. * 6 through 10 are taken from the State Fleet stamp sheet with brief background information. 1) A brigantine or schooner-brig is a two-masted sailing ship, of which the forward mast is square-rigged, while the aft mast carries one or two square sails at the top. The ship is valued for its maneuverability. 2) A pink as a beach vessel was already in use by sea fishermen on the North Sea in the 17th, 18th, and 19th centuries. The ship has a flat bottom, allowing the vessel to sail in shallow water. The pink was launched into the sea from the beach and landed back on the beach from the sea. 3) A galleon, as a flat-bottomed vessel, is in service with the merchant navy as a coastal vessel for the transport of goods. 4) The round-built hooker, as a flat-bottomed vessel, usually has two masts, but sometimes three. The ship has a cabin extending above the deck. It is used in the fishing industry. 5) The boatship, also known as a Greenland boat, was in the service of whaling in the 18th century. Longboats hung from the gallows on either side of the ship and were lashed to the ship's sliding beams with oars for protection. 6) At the time when a sailing ship was still used as a gunboat, it carried only one cannon and could easily maneuver in shallow waters. The ship could operate with ease in rivers, allowing it to easily hit inland targets. 7) The function of a yacht for the Committees of Councillors was to inspect fortifications along the major rivers and for official visits. The ship is fully under sail and tows a sloop. It flies three flags with the coat of arms of Holland. The stern is decorated with wood carvings. 8) An advisory yacht is a small, fast-sailing, and lightly armed warship that served in a war fleet during the era of sailing ships to transmit messages and orders. The ship was also used for reconnaissance. 9) A frigate is a three-masted full-rigged ship (sails on yards) that served as half merchant and half warship with an overhanging stern. The ship was propelled by sails or oars. 10) A two-masted war brig lies at anchor with partially hoisted sails. In front of the warship lies a sloop, which is accessible via a downward-hanging ladder. In the background, several sailing ships are visible to the left and right. Perhaps ships of the States' fleet partially depicted here are visible in the background of the naval heroes stamps.
