The vintage patina is wonderful and it appears that this was painted on a reclaimed wooden board, along the bottom are two rows of tacks that were painted over and must have served a purpose for the board in a previous life. The Black Cat Fireworks company was started in the 1940's and is still in operation today. The sign is 8' long x 18" high and 7/8" thick. There was a crack in the board so we repaired that and added the cross braces on the back for stability. No it is super sturdy.
We think this sign is from the mid 1900's. You can see this sign in person at the Columbia Rivertowne Antique Center, Columbia, PA. The item "Vintage Fireworks Painted Wooden Advertising Sign Black Cat Shipping Available" is in sale since Tuesday, September 17, 2019.
