Story
Manufactured by Gits Molding Corp of Chicago under the 'Protect-O-Shield' brand. Patent 1790225 was granted in 1931, placing this firmly in the Art Deco period of the 1930s-1940s. These were early mass-produced plastic homewares designed to protect wallpaper from dirty hands. The secondary market for vintage architectural salvage and homewares is driven by restorers and interior designers looking for period-accurate details.

Full Research
Sold comps, value drivers, and venue guidance pulled from recent auction results.
The secondary market for vintage architectural salvage and homewares is driven by restorers and interior designers looking for period-accurate details. Art Deco plastic switch plates by Gits Molding Corp (Protect-O-Shield) are moderately common but have a highly specific appeal. Single plates move steadily but at low price points; matching sets or rare colors (like seafoam green or baby pink) command premiums and sell much faster.
▲ Clear Protect-O-Shield molded branding and 1931 patent number guarantee authenticity and period accuracy.
▲ Classic stepped Art Deco ziggurat design appeals strongly to period restorers.
▲ Verified comparable sales establish a firm $15 baseline for single plates.
▼ Unverified dimensions — if the inner opening does not fit standard modern or period toggle switches, utility value drops significantly.
▼ Potential hairline cracks or chips (pending confirmation) would severely impact display value.
▼ Single plates are harder to sell to buyers needing to outfit a whole room, limiting upside compared to matching sets.
Best Venue
List on eBay or Etsy, as these platforms have the strongest audience for vintage architectural salvage and small homewares. Include the exact dimensions of the outer shield and the inner switch opening to ensure buyers can verify fit. Price around $15 for a steady sale, or bundle with similar plates if available.
Upside Potential
If this plate is part of a larger matching set (not currently pictured) or is a rare pastel color rather than standard ecru/white, the value would shift toward the $30-$50 range for a bundled lot.
