Oscar French furniture bookcase

French Oscar furniture bookcase from the 60s-70s. The doors and windows slide perfectly. Furniture that can be dismantled and modularized as desired.

Given its age, it may have some defects linked to normal wear but this remains discreet all the same. 4 blocks with sliding doors: depth 35, width 73, height 43.5, height under shelf 21.5, above 19.5.
