Today's lockdown deck doesn't have a name or logo on any of the 32 cards, nor is there a tax stamp on the ace of hearts. But we found a similar deck on the WWPCM site and Sacha attributes this deck to Frommann & Bunte. Maybe he got his information from the person who provided the images. It's dated as 1872 there. The courts look a bit like a standard pattern, but I find their clothing a bit too elaborate and detailed for that. The courts all have a small suit sign (on their chains or necklaces) but I couldn't find that detail on the JC.
