Recently, I spend a lot of time researching 20s to 50s circa wallet design. Understand that during that era, change, cheque and cash are the only essential items in the wallet, sometime keys….
The ergonomics shape in the front plays the most iimportant details.
Detachable key hook with a build in rein.
Basic change compartment, notes and also a larger slot for cheques.
Things are simpler during the early days, the makers then, only focus on 3 thing that we OGL always do….. durability, functional, simple….
