"May I have your autograph?"
Translation:Mag ik jouw handtekening?
Yes, when "mogen" is used without another verb, but with a direct object, then "hebben" is usually implied.
If it used without an another verb but with a preposition such as "naar", "in", "op" etc., then the verb "gaan" (to go ) is implied. For example:
- Ik mag niet naar de bioscoop - I am not allowed to go to the cinema.
