The Texaco Marine Lubricants sign doesn't look right ? (Page 2). Curved Texaco is all bunched at the top, missing a boat? Certainly not like any I've seen. Maybe they made different versions ? Looks like an oil rack sign.
Missing Sailboat between the 2 larger boats & the A in Texaco is missing the white. Appears to be a Painted sign.
You are correct it was a hand painted sign; in person you can tell, but looks good to display as such. They were selling as a hand painted sign, NOT trying to sell it as an original.
