One of the cool things associated with drive-in theaters (and to a certain extent with walk-in theaters, too, back in the day) was the calendar card. These were advertising calendars, printed on heavy paper or cardstock, that informed eager drive-in patrons what the theater was showing on what dates. They were often bulk-mailed to every household in the area, or given away at grocery stores and the like.
They were meant to be eye-catching, often printed in two contrasting colors, or on colored paper. Some were a half sheet, some were a full sheet. They often had holes punched in the top, so you could hang them on a nail in your kitchen (this was before the discovery of refrigerator magnets).
I have about 25 original calendar flyers, ranging from 1948 to 1978. They were printed by regional companies that apparently specialized in serving theaters. Some of the ones I have are sample stock that were found when a printing company went out of business.
A couple of people have asked me about the flyers I make for the Cherry Hills Driveway Theater, so I have uploaded a blank one here:
To make this, I took a scan of a 1973 calendar and fiddled with it until it was a skeleton usable for my purposes. Here's what it looked like before I worked it over - I just took the original and pasted in my logo to see how it would look:
You can do the same by pasting your theater's logo into the box at the top and then put ads for the movies you will show in the boxes. To keep it authentic, you should only use the two colors already on the flyer - turquoise and dark brown.
I have some other similar scans of original flyers, so if you want to do this yourself and want something no one else has used yet, send me a private message and I'll send you a scan. Here's a sample:
