The Bubble Calendar is a fun and innovative handmade calendar that comes out of Brooklyn, NY. It’s a big (122cm x 46cm) poster calendar that has all days of the week with all major (US) holidays marked; weekends are also bolded for quick reference. But the best part is there’s a bubble to pop every day. The type is set in Helvetica Neue, with the plastic version printed on thick clear acetate, with both vertical and horizontal verisons available.
