Another vote for lith printing: I've got some part used boxes of Agfa Record Rapid, some blue label, some white (later, no cadmium IIRC). No idea how old, but it dates back to a time when 25 sheets of 8x10 cost 6.29 and was available in a high street photography shop!

Completely useless for conventional printing - even with no exposure it goes very dark grey after 30 seconds in the developer. On the other hand, with generous exposure, it develops a beautifully smooth sepia image in lith developer, albeit very slowly, and no fogging of the highlights.
