Vintage Rosenthal Studio-Linie porcelain ashtray Colonial Man w/ Spy Glass telescope Germany

For your consideration is this vintage Rosenthal Studio Line porcelain ashtray. It came from my parent's estate and belonged to my grandparents, so I estimate they got it on their travels in the 1960s. I have not found any other examples online so don't know if it had an official pattern name. 

It is in excellent vintage condition with no issues to note. Measures 4" wide x 1-3/8” deep.

It will weigh less than 1 lb packed safely. Thank you.
