Crown Central Petroleum Calendar with Thermometer...1970s.

I recently acquired this calendar/thermometer promoting Crown Oil of Baltimore, Maryland. This 70s era item is about 8.5x19.5 inches (21.5Cm x 50Cm). It's in really good shape paint and metal wise, and the thermometer still works.

Since Crown has not issued refills for the calendar in years, it will be a task finding such. The original calendar sheets were in in 3 month pages, and were about 7 5/8x10 inches, with mounting holes of 6 inches apart. That is 20.5Cm x25.5Cm, with the holes being about 15Cm apart.

It is a cool item, that would be even cooler with the calendar pages. If anyone can help me abtain such pages, I'd be very appreciative! Thanks!
