Too much information
This family aimed to make a warm gesture by welcoming their mother back at the airport after spending considerable time apart. However, when creating a welcome sign, a simple “welcome home” would have sufficed. The middle sign, to put it kindly, appears quite unnecessary.

Nevertheless, there are three family members – a father and two children – and they likely wanted a sign for each of them. So, while the middle sign might be redundant, they couldn’t bring themselves to discard it. If they desired everyone to participate in holding something, they could have opted for a bouquet or balloons.
