Dear [Friend's Name],

I hope this letter finds you well! I wanted to extend an invitation to you to join me for a special event that is happening next weekend. There is a new art exhibition opening at the museum and I thought it would be a great opportunity for us to spend some time together and appreciate some beautiful artwork.

I know how much you enjoy art and culture, so I think you would really enjoy this exhibition. It's going to be a fun and enriching experience, and I couldn't think of a better person to share it with than you.

Let me know if you're interested in joining me, and we can make plans to attend the exhibition together. I'm looking forward to spending some quality time with you and exploring the art world together.

Hope to hear from you soon!

Warm regards,
[Your Name]
