While the license of this work may be compliant with Commons, its usefulness outside the English Wikipedia is unlikely. It should not be copied to Commons unless a specific significant cross-wiki use can be demonstrated. Additional: This image serves only as a sketch (used only on page Talk:Mathematical_induction#Explain_relation_between_Peano.27s_induction_axiom_and_exclusion_of_nonstandard_models_in_article); a beauty version of it still has to be produced; the latter then could be moved to Commons, and the former deleted.
