For example, humor birthday cards with pop_up pages are not only visually impressive, but they are also fun for children or anyone who enjoys interacting with pictures and movable parts. Even the dourest of individuals can be amused by the card's level of detail well after it is first opened by the recipient. These cards are ones that will be treasured for years to come even after that year's birthday.
Humor birthday cards with unusually large shapes and sizes are also very effective ways to heighten a birthday party celebration. Just as how they can hold an enormous amount of content, the cards can also command an equally enormous amount of attention and detail. More importantly, the card's excess space and size will come in handy for hiding special knickknacks and novelty gags or a gift card without being too bulging or tearing the envelope.
