Vintage paint box Grumbacher Gamma Range as is paint box

Vintage Grumbacher box with dried up paint The blue box says Gamma Range Retouch neutral gray. There are three tubes inside, 2, 3, and 4. Sold as is, the paints are hard and I dont know if they can be reactivated or not. I know some people collect vintage art supplies and I would like this to find a home where they can be enjoyed by a collector instead of thrown away. When they were new, the paints were used by photographers to retouch photos and negatives. The box has wear and tear but still neat for decor or photo prop as is. Ships fast! OP88HD6G5R
