Let’s be honest, not all of us are mathematically inclined - and this funny greeting card celebrates those of us who’d rather goof off than study our equations. This illustrated greeting card features a hand-drawn classic calculator in its most-used position: upside down so the screen reads 80081E3 (BOOBIES). Teehee! The naive handwriting-style caption ‘what I learnt in maths’ adds the finishing touch to the funny birthday card, sharing hard truths about our (lack of) education. The retro birthday card prompts a delightful wave of nostalgia from its unique design, and the blank inside is ready for the sender to add their own message and personalise the greeting card for any occasion.
