Butter "fish" Vallerysthal

Vintage "fish" butter in transparent molded glass from vallerysthal, signed, dating from the years 1960-70, in good condition despite two impacts due to friction between the lid and the base but frankly not very visible... I tried to photograph them but it's not easy to see... It seems to me that it is a rare piece because I did not find it on the internet... It is 20cm long and 7cm widest.
