Stamp-field comparator

Choose a stamp field (1–100) and compare its appearance on all seven printing plates side by side — exactly the way a plate is attributed for a particular stamp. The images are registered on the red frame of the design, so the details sit in the same place on every plate. Hovering over an image magnifies the drawing (2.6×) with the loupe following the cursor; the “XL previews” toggle enlarges the whole grid, and clicking opens the full resolution.
