Vintage Omega Weber‎ Costello Colored Chalkboard Chalk Box Chicago School Fair

Vintage Omega Mega Chalkboard Chalk by Weber Costello Co. comes in its original mid-century graphic box. This set features an assortment of colored chalk sticks, including shades of blue, green, pink, orange, and violet. The box itself is a fantastic piece of Chicago school history, manufactured in Chicago Heights, Illinois, with classic typography and a vibrant red, black, and cream color scheme. While the box shows significant wear and a hole in the front, the remaining chalk pieces retain their bold, dusty pigments, making this a great find for collectors of vintage office supplies or classroom memorabilia.
