Good evening Gary and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your questions.
This is because our Calendar does not use an actual page, but rather a complex WordPress Archive system.
The good news is that you can still customize pretty much any view the way you want.
You might want to read our Themer’s guide to get a sense of how that works.
Another option is to snag a copy of our the Events Calendar Pro https://theeventscalendar.com/product/wordpress-events-calendar-pro/ plugin.
This lets you use full-calendar shortcodes which is another way you could add graphics at the top of the page: https://theeventscalendar.com/knowledgebase/embedding-calendar-views-tribe_events-shortcode/
Let me know if that helps.
Have a great day!
Geoff B.
