Once, I made a drawing for my son. It had fire trucks, diggers, dinos, and basically anything he likes (including pasta!). When I painted his name over it, his face lit up and that huge smile is still engraved in my memory. He requested for it to be taped over his headboard and stayed there until it turned grey from sticky little fingers inspecting it on a daily basis.
That's how I came up with the idea of making personalized posters.
There's something about writing their name on it, means that they own it! Their very own dinos, butterflies, fire trucks... it draws a smile in their face :)
Here you can see him trying to convince us to hang his new poster in our living room.
