Pair of vases 1970's fat lava retro design mid century

Spectacular, rare and very well matched pair of vases from the late 1960s-early 1970's of german manufacture of fat lava type. They are from my personal collection. The large east of jasba germany and is identified n-322-13-26, has a decoration with spirals and quite unique red-orange, green, yellow, black colors (this model is found more frequently of orange or brown color); size 26 cm height and about 17 cm deep. The smallest is from scheurich w.germany and is identified 275-20, it is bright yellow in color and almost neon black; I only know this one with this shade (it is found in a multitude of more or less successful colors including a faded lighter yellow). Size 20cm height and 9cm depth. They were exhibited at home together, so I preferred not to separate them because they respond very well and are very decorative as well.
