The Ica Minimum Palmos (9x12, model 456) is an early 20th-century German folding plate camera taking 9x12cm sheet film or plates. It was a compact folding design positioned within Ica's pre-merger range before the company was absorbed into Zeiss Ikon in 1926.

Reference data for this model is extremely thin: a single recorded UK auction hammer result from 1998 sold for £34, which is far too dated and isolated to indicate what an Ica Minimum Palmos 456 is worth today. Anyone trying to value or price one in 2026 should treat that figure as historical only and look for fresh saleroom comparables before deciding what the camera sells for.
