Shown here is a rocket fuel handler's suit. Given that the insert on the back of the garment specifies that special care must be taken to avoid contact with both fuel and oxidizer, it is likely that the time period of its use dates from the 1950s or 1960s. During that time, all large-scale launch vehicles used liquid propellants, typically nitric acid and aniline, kerosene and liquid oxygen, and by the late 1960s, liquid hydrogen and liquid oxygen. In these cases, fueling had to be completed just prior to launch. Super cooled temperatures and volatility--especially in the case of liquid hydrogen--required careful handling.
The manufacturer and donor are presently unknown.
