Here is a picture without the border.
I had so much fun with it that I decided to make another. I chose a different Lichtenstein painting this time ("Fast Car") and blew it up to 4' x 5'.
A little background on the process.
Step 1: Buy lots of legos. I purchased them from a online lego supermarket (www.bricklink.com). They have pretty much every type of lego you would ever need and the prices are good.
Step 2: I built the back from a sheet of plywood and some 1" x 2" wood bracers nailed to the back.
Step 3: I then glued lego base plates over the entire wooden board in order to be able to stick the lego pieces on.
Step 4: The tedious part! I gridded out a 8.5" x 11" picture of the painting and just like that project most of you have done in grade school I recreated each square of the sheet in legos on the main board. I had to order parts several times as I never ordered enough legos at once.
Step 5: The finishing touches! The boarder is made from black flat tile legos stuck on in a 2" boarder around the picture. The boarder overhangs the board slightly to conceal the wood behind. After the legos were all on, I painted the boarders of the wood for a nice finish
This project was very time consuming but still a lot of fun. Overall cost was around $350 for the first one and $600 for the second.
