Your 100% correct Marty, there are not many young people interested in old stuff, they all want to buy from Ikea, use it and throw it away. I have a lot of stuff mostly old being I have collected for almost 50 years. The good stuff is never hard to sell, so my advice to any aspiring collector is to collect the best.
All of the mediocre stuff should just be left in the ground for the future.
so, planeguy2, the blue one is a re imagination of the "Brookfield Baby Face" cream top milk bottle, a very popular and sought after vintage/antique milk bottle from the early days of milk bottles and it was a popular collectible of the 1960-70's bottle hobby then monstrous quantities of reproductions from various glass houses all over the world flooded the market like the one you have shown. The red one is a Wheaton..... a very prolific glass house that manufactured and might even still classic bottles for Avon and Bradleys and Alexanders and sooooo many other retailers both in catalogue and department stores in the 1960's through the 1990's and later. My Grandmother and mum, and aunties all had them and you will find dozens to hundreds if you spend a day in summer trolling the yard and garage sale circuits in any town
